Bilitest for newborns. The norm of indicators, price, where to buy, how to use

Bilitest is a non-invasive research method that allows you to determine the level of bilirubin in newborns. The diagnosis is safe and has no contraindications.

What is bilirubin? Norms of indicators for newborns by day and month

Bilirubin is a bile pigment, formed as a result of the breakdown of red blood cells. This pigment has a yellow-brown color, due to which, with the development of pathologies associated with an increase in the level of bilirubin, the skin becomes yellow.

The pigment is excreted mainly in the urine and feces under the influence of liver enzymes. Normally, there is a small amount of bilirubin. However, with the development of various pathologies, the indicators can increase significantly.

Child's age	Rate (μmol / l)
Newborn babies (up to one day)	50-60
Newborns from 2 to 7 days	Up to 256
Children from 7 to 14 days old	60 to 100
Babies up to 21 days	8.5 to 20.5
Newborns between the ages of 1 and 2 months	8.5 to 20.5

At birth, indicators of bile pigment in children born prematurely range from 70 to 110 μmol / l, in those born on time - from 50 to 60 μmol / l. To determine the indicators, a specific diagnostic method can be used, otherwise referred to as the Cramer scale.

Indicators and manifestations:

• The formation of yellowness in the area of ​​the child's head is 100 μmol / l.
• Yellowing of the upper body - 150 μmol / L.
• Yellowness extends to the lower body, including the buttocks and thighs - 200 μmol / L.
• Yellowing of the hands and feet - 250 μmol / l.
• Coloring of the skin and the whole body in yellow color - more than 250 μmol / l.

The higher the indicators, the more likely the development of pathological processes in the child in the area of ​​the liver and gallbladder (dyskinesia). In the absence of signs of the disease, the level of bile pigment in the blood returns to normal after 2-3 weeks after the birth of the child.

Causes and consequences of deviations of indicators from the norm

Bilitest for newborns is applied regardless of whether signs of illness are present or not. The device is necessary for constant monitoring and monitoring of the condition of the baby for the first few weeks after birth.

According to statistics, the pathological form of jaundice develops in 5-7% of children. The disease develops against the background of the collapse of fetal hemoglobin, which provokes toxic damage to the body.

Possible reasons:

• Hemolytic disease. Pathology develops against the background of incompatibility of the Rh factor of the mother and the child.
• The presence of congenital infectious diseases in a child. Viral agents reduce the binding capacity of bilirubin, which leads to the development of parenchymal jaundice.
• Premature birth.
• The presence of diabetes mellitus in a pregnant woman, including the development of the disease during pregnancy.
• Hereditary diseases or congenital abnormalities. Pathology develops against the background of genetic abnormalities associated with the formation and production of liver enzymes.
• Endocrine diseases in a child.
• Hemorrhagic processes in a newborn.
• Taking medications during pregnancy, using antibiotics in a child.
• Congenital pathologies of the biliary tract - dyskinesia, obstruction.
• Severe liver disease in a newborn.

Twins are also at risk.

Untimely treatment can cause various complications and consequences that are dangerous to the health and life of the child.

Consequences:

• developmental delay - physical, psychoemotional;
• hearing impairment, up to and including its complete loss;
• convulsive state;
• paralysis;
• toxic damage to the body;
• nuclear jaundice is a severe disorder accompanied by damage to the central nervous system.

Ultimately, the disease can lead to the development of cerebral palsy (cerebral palsy). At the first signs of the disease, it is necessary to contact the attending specialist for additional diagnostics and treatment. Prolonged elevated bilirubin levels require immediate treatment.

What is a bilitest?

Bilitest is a high-tech device used to measure blood bilirubin levels in newborns. In this case, the procedure is carried out at home.

The device is a miniature electronic device equipped with a special indicator, with the help of which the measurement procedure is carried out. The device allows you to determine the concentration of bile pigment in the subcutaneous layers of a child.

Advantages and disadvantages of the device

The main advantage of the device is its portability and compactness. In this case, the device is intended for home use.

Advantages:

• fully automated process;
• no need for additional configuration of the device;
• minimum error;
• convenience and ease of maintenance of the device;
• the speed of the procedure is no more than 2-3 seconds;
• retesting is possible 5-7 seconds after the previous measurement;
• the battery lasts for 100 thousand. measurements;
• no need for blood sampling (non-invasiveness);
• no power on / off required.

The disadvantages include the measurement error if the child has a slightly dark or, conversely, too light skin. Also, the analyzer shows the results of total bilirubin in the blood, without dividing it into direct and indirect.

Characteristics

The device has a wide measurement range - from 0 to 400 μmol / L. In this case, the number of measurements that can be carried out using 3 batteries is at least 100 thousand. once.

Characteristics and parameters:

• The device weighs 300 g in a complete set. The weight of the device without a complete set is 150 g.
• Dimensions - 171 × 70 × 37 mm.
• Batteries - AAA lithium batteries (3 pcs.).
• The number of digits on the digital panel is 2.
• The correlation coefficient with serum bilirubin is 0.9.

  

The device is convenient and practical to use and does not take up much space.

What is included?

Bilitest for newborns is allowed to be used only after familiarization with the rules of operation of the device. The analyzer kit includes the instrument itself, a case-packing, 2 control light filters, a special glass set and 3 pcs. batteries of 1.5 V.

The package also contains instructions for using the device, methods of testing the device for operability, as well as guidelines.

Device performance monitoring

Before using the analyzer, it is necessary to check the operability of the device. For the procedure, special optical control measures are located on the case. No other control measures are required for the device operability.

Preparation for analysis

Prepare the instrument before performing the analysis. To do this, the device must be removed from the case. In this case, there is no need to turn on the analyzer, since it is already ready for use.

It is recommended to wipe the surface of the light guide head with a clean dry cloth or a napkin moistened with alcohol solution. After that, the treated surface must be wiped dry with a clean cloth. The procedure should be carried out before each measurement. It is allowed to take measurements with the device only after the alcohol solution has completely dried.

Patients are also encouraged to prepare for the test. To do this, you should refrain from eating a few hours before the start of the procedure. In a few days it is necessary to stop taking medications that affect the level of bilirubin in the blood.

The analysis should be carried out in the morning, 1-2 hours after waking up.

How to use the analyzer?

Bilitest for newborns must be used in accordance with the recommendations of a specialist and the instructions of the instruction manual.

To carry out the analysis, it is necessary to lean the moving part of the head of the device against the surface of the child's skin, and then press the device until a sound signal appears. The device must be held in the fixed position until the end of the sound signal (usually 1-3 s). At the end, the device must be taken away from the skin surface.

The measurement values ​​are shown on the display for 30 seconds, after which the analyzer goes into the "standby" mode. To determine the exact indicators, the procedure is recommended to be repeated at least 3 times on different areas of the skin. In this case, it is necessary to choose an average value.

When the “-” symbol is displayed on the display, the measurement needs to be repeated, since the device may have been removed from the skin surface before the end of the sound signal. At the end of the procedure, the device must be put back into the case, having previously treated the movable head with an alcohol solution. The device does not require shutdown.

Precautionary measures

Safety precautions must be taken when working with the device. Thus, it is not recommended to use the analyzer by persons who are not familiar with the instructions and rules for working with the device.

It is also forbidden to expose the device to any mechanical damage, shock. Do not open the analyzer case (packaging) in warm rooms after a long stay in frost. It is recommended to observe an interval of at least 4 hours.

When carrying out the analysis, it is necessary to take preventive measures and precautions for treating the working element of the device with an alcohol solution. It is recommended to store the device in its original packaging.
