Embodiment

[0065] Take 5 fresh samples of whole blood with gradient total bilirubin concentration, each concentration is divided into 3 parts, the first part is tested for total bilirubin by biochemical analysis, the second part is determined by the standard curve of total bilirubin, and the third part is determined by the total bilirubin standard curve. Parts are tested with the total bilirubin test card, and the obtained results are compared with the biochemical analysis. The obtained test data and standard curve are as follows:

[0066]

[0067]

[0068] The test data is confirmed by the standard curve. From the test data, it can be concluded that the signal value of the test has good repeatability. Since the signal of reflected light intensity is detected, the higher the total bilirubin concentration, the darker the color of the reaction color. The more light intensity absorbed, the less reflected, the smaller the signal value; the lower the total bilirubin concentration, the la...

Abstract

The invention provides a total bilirubin test card and a manufacturing method thereof, the test card comprises an upper cover, a gauze, a blood absorbing pad, a blood filtering film, a color developing film, a PET bottom sheet and a lower cover, and the total bilirubin test card is formed by assembling the upper cover, the gauze, the blood absorbing pad, the blood filtering film, the color developing film, the PET bottom sheet and the lower cover from top to bottom in sequence. According to the invention, the total bilirubin concentration in human serum can be rapidly, conveniently and accurately measured.

Description

technical field [0001] The technical field of detection equipment of the present invention, in particular, relates to a total bilirubin test card and a manufacturing method thereof. Background technique [0002] Bilirubin is a kind of bile pigment, which is the main pigment in human bile and is orange-yellow. Most of the bilirubin in the serum is derived from the hemoglobin produced after the destruction of aging red blood cells. The glucuronidation in the liver is called direct bilirubin, and the glucuronidation in the liver is called direct bilirubin. What has not been glucuronidated in the liver is called indirect bilirubin, and the sum of the two is bilirubin. [0003] Jaundice is the clinical manifestation of hyperbilirubinemia, that is, when the serum total bilirubin is greatly increased, the human skin, sclera, urine and serum appear yellow, so it is called jaundice. Jaundice can generally be divided into the following categories: (1) Hemolytic jaundice: In hemolyti...
