Measuring procedure

With scarificator the heel of new-born is pricked. A drop of blood is taken to hematocrit capillary tube (heparinized). Only 40-70 ml of blood is enough (1 ml for biochemical analysis). Precise quantity is not essential. Capillary tube is closed from one side by a usual children plasticine or special hermetic and is placed into hematocrit centrifuge. After 2-3 min centrifuging capillary tube is taken out and scratched on the separation boundary between plasma and erythrocyte mass. Capillary tube part with plasma is brought to one of sections (slits) of 10-sectional reusable optical cuvette . Due to capillary forces plasma is itself sucked into the cuvette sectional slit. The necessary section of optical cuvette is positioned inside the device with the help of a handle for cuvette positioning. When necessary section is positioned the key "Measuring" shall be depressed. Measuring time takes 1 sec. Measured result for general bilirubin concentration in the human blood is read from LC digital display in mmole/l. The whole process from taking blood sample to final measuring takes 3-4 min.

Advantages of photometric measuring of bilirubin concentration are evident. This is a direct measuring method. It does not demand reagents. Blood sample volume 10 times less than for biochemical methods. Due to this blood sample can be taken by a simple pricking of infant skin with a scarificator. No need to take the blood from veins.

BILIMET successfully supplements non-invasive method of measuring bilirubin with BILITEST. If after primary routine measurement with BILITEST there will be discovered that an infant comes into the hyperbilirubinemia risk group, BILITEST's measurement can be supported by the direct measurement of the blood sample with the help of BILIMET. After BILIMET use only non-invasive periodical checking with BILITEST will be enough.
