What is the primary purpose of an amber microtainer?

The amber microtainer is specifically designed to protect light-sensitive tests from exposure to light, which can cause degradation of certain analytes. This is particularly important for tests such as bilirubin and certain vitamins that are sensitive to light, as prolonged exposure can lead to inaccurate results. The amber color filters out light, ensuring that the integrity of the sample is maintained during storage and handling.

While collecting blood samples for glucose testing, preventing hemolysis, and labeling samples accurately are important considerations in the laboratory setting, they are not the primary function of an amber microtainer. The distinctive amber coloration is what sets it apart as a tool specifically for protecting samples from light damage.
