What is the purpose of amber coloring on the microcollection container?

• A. Increases light transmission
• B. Keeps contents cool
• C. Prevents contamination
• D. Reduces light transmission

Answer: (D)

Light exposure can degrade certain blood components, so amber-colored containers reduce light transmission to protect those samples. The amber filter blocks much of the visible light that can trigger photochemical reactions, helping preserve analytes that are sensitive to light (for example, bilirubin and some vitamins) until analysis. It doesn’t cool the contents, and while maintaining sterility is essential, color alone doesn’t prevent contamination.
