What does it mean Ph of urine
Ph level in urine (acidity) in urine determined by the content of hydrogen ions, which are decomposition products of the inorganic compounds. According to figures to draw conclusions about the cleaning ability of the kidneys, blood purification. Normally allocated bladder processed fluid consists of 96-97% of urine, 4.3% salts, nitrogenous compounds.
The output substances have acid-base characteristics. With the prevalence of acid (. Ph below 5 units) credited urine, alkaline (ph over 8.0) - alkalizing, simultaneously neutralize excess values due to the urine excretion minerals and organic compounds from bone tissue.
Acidity pH OK
Ph urine (normal adult population, on average ranging from 5.1 to 7,1ed) can be changed in a day:
- morning - 5.2 - 5.8;
- day - 6.4 - 6.8;
- night - 6.5 - 7.
In men, the value of acidity lower (from 5.1 - 5.6 in the morning hours from 6.1 to 6.6 in the evening).
Reduction of 0.4- 0.6 for pathologies is not male, due to the predominance in the diet protein foods (meat, egg white, high cheese fat), virtually complete are out fruit and vegetable dishes, vegetables, and high enthusiasm hard physical activity designed to build muscle body weight.
For women, the rate is from ph 5.3 - 5.8 after waking up from 6.7 to 7.2 before bedtime. Excess digits to 0.3-0.7 units. - normal and most often occurs in the low-carb diet fans, the large consumption of saline fluid.
In analyzes of expectant mothers found readings of 4.5 to 8.1 units. On the values of acidity affects the body's hormonal changes, changes in diet, toxemia. These figures do not consider the pathology ph in a good state of health of women who do not require medication adjustments.
Table acidity values:
| Age | U |
| children born before the line | 4,7 – 5,5 |
| newborns | 5,4 – 6,1 |
| 2-month baby who are breastfed | 7,1 – 7,7 |
| children, feeding with formula | 5,6 – 7,0 |
| to 2 years of age and older, adults of both sexes | 5,4 – 7,0 |
| in a child's timeout | 4,3 – 8,1 |
The reasons for lowering ph (acidification)
Acidification (aciduria) appears to decrease pH level of 5.0 and below.
In the following cases:
- The predominance of the daily nutritional diet of protein foods. It manifested in the propensity to consume large amounts of meat products, a decrease in the green menu, vegetables, fruit.
- Enhanced physical exercise, aimed at weight gain.
- Reducing consumed during the day the liquid (less than 0.8 l.).
- On the quality of selected food products and beverages. A high content of food additives, dyes, provokes cholesterol lowering pH.
- The appearance of fever, chills, fever, accompanying viral infections of upper respiratory tract.
- Uncontrolled receiving diuretics. Particularly characteristic for female fascinated teas, tablets, whose action is directed at reducing excess body weight.
- Pelvic infections, gynecological problems.
- Daily round decision ascorbic acid in order to maintain immunity in the autumn-winter period.
- Infectious inflammation, which are based on E. coli.
- Renal insufficiency.
- Sepsis.
- Prolonged fasting, uncontrolled passions A low-calorie days, anorexia.
- Alcoholism.
- Diabetes when above the threshold dextrose content in the blood fluid at 5 ml. / Mol or more.
- Hazardous conditions, increased air temperature in the workplace.
- Allergies in children.
For newborn babies pH 5,0 is the norm. Does not require treatment, increases as the child gets older.
Aciduria, lasting more than 14-20 days, causes a fear suggesting infectious diseases of the urogenital system, kidneys, presence of stones and sand in the bladder.
Reasons for increasing ph (alkalization)
Ph in the urine, if a change from the norm medical conditions seen in the direction of increasing values in medical practice by the term "Alkaluriya" is characterized by an increase in numbers of 8.0 or more u This condition is often accompanied by severe headache, dizziness, nausea, vomiting, muddled consciousness, fainting.
Occurs when:
- Low calorie vegetarian diet (especially dangerous raw food) used saline liquid in an amount considerably exceeding the permissible (over 2 liters. per day).
- Inflammatory diseases of the urinary organs, accompanied by cystitis.
- Insufficient adrenal activity, hormonal disorders, uncontrolled taking hormonal contraceptives.
- Diseases of the gastrointestinal tract in chronic and acute form (pancreatitis, cholecystitis, cholelithiasis)
- Dysfunctions of the endocrine system, accompanied by metabolic disorders, hypertension.
- Raising the level of phosphorus compounds in the blood fluid.
- Insufficient amount of calcium in the body.
- Receiving Phenobarbital. Alkalization occurs when outputting kidney preparations from decomposition products of the organism.
Ph urine. The norm may be distorted after receiving fenobrabitala. - In the postoperative period.
- Rickets.
- Vomiting, toxicosis pregnant.
- Diarrhea.
- Toxicological lesions of the body, accompanied by disorder chair, dehydration.
Alkalization of urine comes with congenital abnormalities of the kidneys and endocrine system. In pregnant women, the pH value of 8.1 or more is a symptom of hormonal changes the body, caused by their calcium deficiency, toxicity.
Indications for an overall analysis of urine
Common clinical and diagnostic analysis of urine is assigned to monitor the internal state of the body, functioning kidneys and urinary system. Healthy people are advised to undergo the procedure as a preventive measure not less than 1 time in 6-7 months.
It is mandatory physician prescribes the study at:
- renal dysfunction. To compile a dynamic picture of the patient's condition and the correction of the therapy.
- Bladder infections, ducts, adnexitis, accompanied by frequent urination
- Diabetes, hypoglycemia, dextrose level is exceeded in a liquid blood, a smell of nitrogen during urination.
- Once transferred angina, scarlet fever, diseases caused by staphylococcal wand.
- Strong pain spasms in the kidneys, gall bladder, separation of sand.
- Gallstones, pancreatitis.
- Reduction process after the lane operation.
- During pregnancy, the health of the expectant mother control after delivery.
- Endocrine disorders, obesity, elevated levels of blood pressure.
- Long non-healing wounds, cuts, injuries.
- Preventive medical examinations, especially patients working for food production and in harmful conditions.
During the medical treatment of kidney, bladder, endocrine disorders OAM is assigned at least the 1st time in a month. Pregnant women pass analysis 1 time per month 1-2 rd trimester, once a week in the 3 rd trimester.
How to get tested
Ph urine (normal values depends on the correct preparation procedures, collection and delivery of the biological material) is determined at the time assays, following special preparatory process.
He is such a:
- Urine is collected in a special container, issued in the medical facility. To collect the urine in the home is purchased sterile bulb at the pharmacy. If it is impossible to use the container can purchase small glass container lid, washed with soap and disinfected in boiling water. Container for collecting urine to be dry.
- The natural dyes (carrots, beets) are excluded from food for one day, alcohol, diuretics herbal teas teas, medicines, except when the analysis is carried out to control the passage of drug therapy.
- Women should not take the analysis at the time of the menstrual cycle due to the ingress of blood clots, giving reason to assume the wrong diagnosis.
- Mandatory hygienic toilet genitals before urinating. female persons is recommended to close the vagina cotton disk to avoid the penetration of bacteria in urine.
Taking material:
- Urine is collected in the morning, immediately after waking up.
- Keep the collected urine should be no longer than 160 minutes.
- It is impossible to cool the biomaterial. Lower temperatures favor the appearance of salts giving rise to an erroneous diagnosis "renal failure" and is not required of the patient to treatment.
How to determine the ph at home
Ph urine (normal values determined in the home, if necessary) is installed in the following ways:
1. Litmus paper. To perform the test using a strip of blue and red colors, soaked in a special solution. Lowered into the tank with the liquid they need to turn 1-3 seconds. Remove the paper placed on a clean, dry surface is not available for exposure to ultraviolet rays upwards reagent.
Results of research study after 3 min .:
- indicator hue is not changed - neutral environment;
- change of color of both strips - sour alkaline;
- bluish red - alkaline;
- redness of the blue - sour.
Ph value of digits when this analysis is impossible to establish.
2. Magarshak method. 2 cap. of urine was mixed with 0.1% solution of neutral red and methylene blue alcohol.. In color precipitate formed within 2 seconds, set the level of ph:
- dark violet - 6.2 - 6.5;
- light purple - 6,7 - 7,1;
- gray - 7.4.
3. bromoethyl method. 3 Cap. urine diluted in 20 mg of bromoethyl indicator diluted with water. The set value is obtained by the color liquid. The method is not reliable.
4. ionometer - the most reliable option, which is a device that is placed in the morning urine. Accurately determine the level of acidity in the figures, displaying readings on the monitor.
5. The indicator strip - the most common method used in the home and in the laboratory, which allows to change the color of the plate, impregnated with reagent set ph level of 4.9 to 9.1 units.
What is the test strips for urine analysis
Ph urine (reading rate) is determined using a tracer test strips representing plates with a plastic or paper base 5 by 6-13 cm, applied with the chemical reagent. Upon contact with the hydrogen ions, secreted with the urine, the indicator changes color, making it possible to set the level of acidity in Figures 4.9 to 9,1 ph.
The choice of drug depends on the expected or specified pathology. Depending on the required values obtained in the analysis, can be used odnoindikatornye strips impregnated single reagent or multiindikatornye plate - making it possible to simultaneously check multiple indicators.
Complete home study are:
- cylindrical plastic packaging with 25-150 reagent strips;
- Detailed instructions for use;
- sorbent to remove excess liquid;
- tint scale to establish the results of the study (the most commonly applied to the package).
Home test is not able to fully replace the clinical and laboratory procedures, but allows Self-control readings in correcting any drug therapy pathologies.
Types of test strips
Test strips differ:
1. In the country the manufacturer:
- Swiss «Mcral-Test»
- Korean «Uriscan»;
- Russian "Biosernor", "Bioskan"
- Canadian «Multichech»;
- American «UrineRS»;
2. According to the component scans:
- dextrose;
- ketones;
- bilirubin;
- protein;
- creatinine;
- urobilinogen
- acidity;
- leukocytes,
- erythrocytes
- structure density
3. Inflicted by the number of chemicals, in accordance with what is given the opportunity to monitor the values of several indicators, such as:
- blood,
- protein;
- level of acidity;
- nitrites;
- density;
- glucose;
- erythrocytes
Terms of Use test strips
Ph of urine is easily determined using the reagent test strips at home.
Preparation for the procedure:
- Pulling the strip, do not touch the display to the fingertips of the plate.
- Collect morning portion of urine in a sterile container, having in front of this outer hygienic toilet genitalia. Do not do the test during the critical days.
- Mix the urine, eliminating the possibility of sediment.
- Diagnose at a temperature of 15 to 25 degrees. Reduced numbers of the environment can cause false indicators.
- Do not use urine collected more than 2 hours ago. The error in this case, values up to 50%.
- Do not use a strip more than once.
- Do not hold the plate in the urine over a specified time in the instructions to avoid incorrect results of the study.
- Do not use devices that have expired.
- Avoid UV diagnostic color scale arranged on a tube.
Carrying out the procedure:
- Gently remove the strip from the plastic box.
- Stir urine by eliminating the salts precipitate.
- Immerse plate in a container for 1-3 seconds.
- Pull indicator remove excess liquid sorbents or tapped strip of container edge.
- Place the dough on a dry surface of the reactant side up.
- Rate of indicators after 1-3 min. on color scale: Orange - 4.9-5.0; Saturated Yellow - 6.0; Daffodil - 6.5; lime - 7.0; pale green - 7.5; emerald - 8.0; bog-green - 8.5.
- Do not exceed the waiting time result. Analysis values may change when exposed to air, UV light.
Acidity is determined by 1 every 3-4 days. It is advisable to conduct research in the same time (just after the morning rise), because during the day the figures vary greatly. Shear rates over 2 weeks in the direction of acidification or alkalization is necessary to consult a general practitioner, to pass a comprehensive medical examination
And methods for reducing the acidity level
Promotes the normalization of the change in daily diet, use of medications, correcting dysfunction of internal organs, eliminate from the diet of cholesterol-rich foods, food additives, dyes.
When urine acidification assigned diet of neutral and negatively-acid foods on a scale PRAL (calculation of the potential renal acid load).
According to medical research when a tendency to alkadurii necessary to reduce the consumption of food belkovosoderzhaschey, expand the number of eaten per day of vegetables, fruits, prefer drinking regimen containing mineralized water without aerating containing molecule potassium, magnesium.
It is recommended to eat:
- Products having zero PRAL:
- milk products;
- cream, vegetable fat;
- cucumbers;
- ice cream;
- tea;
- honey.
- Negative acidity scale PRAL:
- greenery;
- fruit and vegetable nectars;
- vegetables;
- mushrooms;
- fruits;
- red and white wines;
- mineralized water;
- coffee.
Table negative-acid food:
| Food | RRAL (mEkv) |
| tomatoes | -3,2 |
| onion | -1,6 |
| zucchini | -3,3 |
| spinach | -14 |
| carrot | -4,8 |
| celery | -5,3 |
| potatoes | -4,3 |
| cucumbers | -0,7 |
| apples | -2,3 |
| citrus | -2,6 |
| kiwi | -4,3 |
| apricots | -4,9 |
| pears | -2,7 |
| bananas | -5,3 |
| raisins | -21 |
| Strawberry | -2,3 |
| black currant | -6,6 |
| cherry | -3,5 |
| watermelon | -1,3 |
For low acid products include bread from the first-class and second-rate flour - 3-12.
In addition to the diet is required:
- Stop peretruzhdaetsya body reinforced physiological loads. It is best to go on sparing sports (jogging, swimming, athletics, cardiovascular).
- Refuse receiving diuretics.
- Do not get carried away with ascorbic acid, prefer other means to raise immunity.
- Exclude from the diet of cholesterol-rich foods, food additives, colourants, manufacturing sweets.
- While maintaining the values characteristic aciduria for more than 2 weeks should consult a doctor to undergo a full medical examination.
It recommended for oshchelachivanija:
- Daily drinking water fasting with lemon juice, lime, apple vinegar.
- Persons suffering from hypertension, should be added to the drink 1/4 tsp baking soda.
- Remove from food desserts, sugar, artificial sweeteners, carbonated lemonade.
- Do not get carried away fatty meat products. Protein can be obtained from poultry, low-fat varieties of fish, soy, cheese, tofu.
- Exclude consumption cholesterol-rich foods, canned fish and meat, smoked delicacies, sausages, frankfurters.
- Include in the diet of low-fat dairy products, cheese.
- Avoid stressful situations.
- Engage in moderate physiological loads, preferring running, swimming, dancing.
- Do not exceed the water requirements, eliminate from the diet of Coca-Cola, Sprite, Mirinda. These drinks promote the excretion of calcium from the body.
- Spend on drink a course of vitamins and minerals.
- Ph test the value of not less than 1-st time in 3-4 days. When you save the evidence specific to alkalurii required medical consultation, a detailed examination of the body, the correction of identified internal pathologies.
Diet for normalization of acidity should consist of 80% and 20% schelocheobrazuyuschih acidifying products.
For the treatment of dysfunctions of the internal organs and systems normalization ph level in urine is of great medical importance. With timely detection of low or high performance Additional laboratory research, medical and nutritional adjustments.
