Which type of blood specimen requires a special handling process to protect it from light?

Bilirubin specimens require a special handling process to protect them from light because bilirubin is light-sensitive and can degrade when exposed to light. This degradation can lead to inaccurate test results, as the concentration of bilirubin in the sample may decrease, ultimately affecting the diagnosis and management of conditions like jaundice or liver dysfunction.

To ensure the integrity of bilirubin specimens, they are often collected in amber-colored tubes or wrapped in aluminum foil if they are collected in clear containers. Other specimens, such as glucose, hematology, and coagulation specimens, do not have the same sensitivity to light and do not require these specific handling precautions, which is why they are not the correct choice in this context. Proper handling of specimens is crucial to obtaining reliable laboratory results.
