Problems solved by technology

The above-mentioned method has the following technical problems: (1) Wen's centrifugation method is a classic definition method, but it cannot completely eliminate the influence of residual plasma, and the accuracy is low, and this method cannot be conveniently combined with other methods, and the amount of sample used (2) The blood cell analyzer method calculates hematocrit by measuring red blood cells, white blood cells, etc., which is mainly calculated by empirical formulas, so that biological variation cannot be measured. In addition, this method needs to use a blood cell analyzer to input Calculated value, it is inconvenient to test HCT ...

Embodiment 1

[0029] This embodiment provides a hematocrit testing system corrected by sodium ions, which is used for testing the hematocrit value in a blood sample, and further for checking the anemia, hemorheology and other conditions of the tester.

[0030] The test system as figure 1 As shown, it includes a sodium ion electrode test unit 1, which is used to measure the sodium ion concentration in the collected blood sample, and an impedance test unit 2, which is used to measure the whole blood impedance of the collected blood sample, and is connected with the sodium ion electrode. The calculation unit 3 of the test unit 1, the impedance test unit 2 circuit or signal connection, the calculation unit 2 is used to receive the sodium ion concentration value measured by the sodium ion electrode test unit 1 and the whole blood impedance value measured by the impedance test unit 2 , and then calculate the hematocrit value of the blood sample according to the formula. In this embodiment, the s...

Embodiment 2

[0034] This embodiment provides a method for testing hematocrit using the system described in Embodiment 1, which includes the following steps:

[0035] The sampling unit 4 transports the collected blood sample to the sodium ion electrode testing unit 1 to test the sodium ion concentration in the blood sample. The sodium ion concentration is quickly tested by the ion-selective electrode method, and the test efficiency is high, the speed is fast, and the operation Convenient and fast.

[0036] The sampling unit 4 transports the collected blood sample to the impedance testing unit 2 to test the whole blood impedance value of the blood sample. The whole blood impedance value is tested by a double-electrode method, that is, the impedance at both ends of the blood sample is directly measured by two electrodes. .

[0037] The calculation unit 3 calculates the hematocrit of the blood sample through the sodium ion concentration and the whole blood impedance value, and the calculation...

Abstract

The invention discloses a sodium ion corrected erythrocyte hematocrit test system and a test method, and the system comprises a sodium ion electrode test unit for measuring the concentration of sodiumions in a blood sample; an impedance test unit for measuring the whole blood impedance of the blood sample; and a calculating unit which is connected with the sodium ion electrode test unit and the impedance test unit and is used for calculating the hematocrit of the blood sample. According to the system, the sodium ion electrode test unit is added to carry out a sodium ion concentration test ina whole blood hematocrit test of an impedance electrode, and the influence of the factor on whole blood impedance is corrected, so that the accuracy of the hematocrit test is improved, and clinical errors are avoided. Meanwhile, the test system is simple in structure, high in test speed, convenient to use, low in price and low in HCT detection cost. The test method is small in error and high in test efficiency and accuracy.

Description

technical field [0001] The invention belongs to the technical field of biological analysis instruments, and relates to a hematocrit test system and a test method, in particular to a sodium ion-corrected impedance method hematocrit test system and a test method. Background technique [0002] Hematocrit, also known as hematocrit (HCT), refers to the volume ratio of the sinking red blood cells to the whole blood measured after a certain amount of anticoagulated whole blood is centrifuged. It is a measure that indirectly reflects the number and volume of red blood cells. easy way. Combined with red blood cell count and hemoglobin content, the average value of red blood cells can be calculated, which is helpful for the morphological classification of anemia, and is of great significance for the diagnosis of anemia, rehydration of dehydrated patients, and blood rheology. [0003] At present, HCT determination methods mainly include Wen's centrifugation method, blood cell analyzer...
