Storage Length of Blood Samples for Common Tests: Factors Influencing Stability of Blood Samples, Proper Storage, and More.

Summary

• Collected blood can be kept for a certain period before testing.
• Proper storage conditions are crucial to maintaining the integrity of the blood samples.
• Different types of blood tests may require different storage lengths.

When blood is collected for testing purposes, it is essential to ensure that it is stored correctly to maintain its integrity. Proper storage conditions are crucial to prevent contamination and ensure accurate Test Results. The length of time that collected blood can be kept before testing varies depending on the type of test being conducted and the storage conditions in which the sample is kept. In this article, we will explore how long blood can be kept before testing and the factors that influence the stability of blood samples.

Factors influencing the stability of blood samples

Several factors can influence the stability of blood samples and determine how long they can be kept before testing. Some of the key factors to consider include:

Type of test

The type of test being conducted is a significant factor in determining how long blood can be kept before testing. Some tests require fresh samples and must be processed immediately, while others can be stored for longer periods before analysis. For example, tests that measure certain enzymes or proteins in the blood may require fresh samples, while tests that measure blood cell counts can be stored for longer periods.

Storage conditions

The storage conditions in which blood samples are kept play a crucial role in determining their stability. Blood samples should be stored at the appropriate temperature to prevent degradation and ensure accurate Test Results. Improper storage conditions, such as exposure to extreme temperatures or light, can lead to the deterioration of blood samples and compromise the validity of Test Results.

Anticoagulants

Anticoagulants are substances that prevent blood from clotting and are often added to blood samples to maintain their liquid state. The type and concentration of anticoagulants used can affect the stability of blood samples and how long they can be kept before testing. It is important to use the appropriate Anticoagulant for the type of test being conducted to ensure accurate results.

Transportation

The transportation of blood samples from the collection site to the testing facility can also impact their stability. Proper handling and transportation procedures should be followed to prevent contamination or deterioration of the samples. Samples should be stored and transported at the recommended temperature to maintain their integrity during transit.

Storage length of blood samples for common tests

The length of time that blood samples can be kept before testing varies depending on the specific test being conducted. Here are some common blood tests and the recommended storage lengths for their samples:

1. Complete Blood Count (CBC): CBC tests measure the number of red and white blood cells, as well as platelets, in the blood. Blood samples for CBC tests can typically be stored for up to 24 hours at room temperature or up to 72 hours in the refrigerator.
2. Basic Metabolic Panel (BMP): BMP tests measure a variety of substances in the blood, such as glucose, electrolytes, and kidney function markers. Blood samples for BMP tests can be stored for up to 24 hours at room temperature or up to 72 hours in the refrigerator.
3. Lipid Panel: Lipid panel tests measure cholesterol levels in the blood. Blood samples for lipid panel tests can be stored for up to 24 hours at room temperature or up to 72 hours in the refrigerator.
4. Liver Function Tests (LFTs): LFTs measure enzymes and proteins in the blood that indicate liver function. Blood samples for LFTs can typically be stored for up to 24 hours at room temperature or up to 72 hours in the refrigerator.

It is important to follow the specific storage recommendations provided by the testing facility or healthcare provider to ensure the accuracy of Test Results. If blood samples are not processed within the recommended storage period, they may need to be recollected to obtain accurate results.

Conclusion

Proper storage of blood samples is essential to maintaining their integrity and ensuring accurate Test Results. The length of time that blood can be kept before testing varies depending on the type of test being conducted and the storage conditions in which the samples are kept. By following recommended storage guidelines and handling procedures, Healthcare Providers can ensure the validity of Test Results and provide quality care to patients.
