6 Proper Blood Collection Methods | Use of Biochemistry Analyzers

1. 1. The blood sample should be transferred into the anticoagulation tube as soon as possible after collection and inverted up and down 3-5 times. This is to ensure that the sample and anticoagulant are well mixed.
2. 2. Whole blood must be analyzed or converted to plasma and serum within 30 minutes of collection. If the test is performed after the sample has been out of the body for a longer period of time, the accuracy of the test results may be affected.
3. 3. do not freeze or shake whole blood samples vigorously in the refrigerator to prevent hemolysis.
4. 4. if the test cannot be performed in time, the plasma and serum should be isolated and stored airtight at 2-8°C away from light. and tested within 24 hours. Stored on ice at -20℃ for a maximum of 30 days. and cannot be repeatedly frozen and thawed. If these restrictions are not met, the analyte concentration may change and the assay results will not be clinically meaningful.
5. To obtain correct glucose results, blood should be collected at least 12 hours after the subject has fasted.
6. The biochemistry analyzer uses anticoagulated whole blood without clots or plasma or serum without hemolysis. seamaty fully automated dry biochemistry analyzer has a built-in centrifugation function. The biochemistry instrument can automatically separate the anticoagulated whole blood from the plasma for testing. Anticoagulated samples should use lithium heparin anticoagulant which has less effect on biochemical tests.
7. 7. sample collection must be operated by professional personnel. Operators should wear protective gloves, masks and work clothes to avoid contaminating the sample.
8. 8. When the sample cannot meet the test requirements or has been contaminated samples should be disposed of in a timely manner in accordance with local regulations. Use special packaging and containers for medical waste, and should have obvious warning signs and warning instructions.

The biochemistry analyzer is a medical device mainly for blood samples. The correct collection of blood samples is critical to the accuracy of the test results. Therefore correct blood collection is very important.
