Why do they take multiple tubes of blood?

Regular blood tests are one of the most important ways to track your overall health.

Getting tested regularly allows you to understand the way your body changes over time and allows you to make informed decisions about your health. But Why do they take multiple tubes of blood?

Firstly, for backup. Many items require different instruments to test, and different items require a certain amount of blood to be consumed, and a small amount can lead to inaccurate results or failure to produce results. Drawing an excessive amount of blood will ensure that there is enough for retesting in case of abnormal results.

Secondly, respond to the need to test different items. Different tests require different colored blood collection tubes. For example, biochemical tests require red-tipped or yellow-tipped tubes, routine blood tests require purple-tipped tubes, and coagulation tests require blue-tipped tubes, so it is not possible to use the same tube of blood to complete all laboratory needs. Even if some tests can be performed with one tube of blood, the same tube of blood is easily contaminated and confused between different laboratories, which can seriously affect the test results.

Thirdly, it is more convenient and faster. The blood volume of a normal person is between 4000-5000ml, and it takes about 2-3ml to drawtube blood, according to the conventional calculation of 5 tubes, the blood drawn is less than one percent of human blood, except in special cases, the amount of blood drawn for medical examination will not affect the normal physiological condition of the patient.

In order to solve the problem of using only a small amount of blood to test routine biochemical items, Seamaty developed and produced a portable automatic dry biochemistry analyzer-SD1.

SD1 automatic dry biochemistry analyzer is a biochemical analysis system integrating routine biochemistry, coagulation, electrolytes, and some immunological items, which can test liver function, kidney function, cardiac muscle, glycolipid, electrolytes, and other items, and only 100 mL of the sample can be added to test multiple items in the plate.
