Which type of specimen container is appropriate for evaluating bilirubin density in amniocentesis?

• A. Dark
• B. Clear
• C. Green
• D. Amber

Answer: (A)

The appropriate specimen container for evaluating bilirubin density in amniocentesis is a dark container. This choice is correct because bilirubin is sensitive to light, and exposure to light can lead to its breakdown, resulting in inaccurate test results. A dark container minimizes light exposure, preserving the integrity of the bilirubin for accurate analysis. In contrast, clear containers allow light to penetrate, which can degrade bilirubin levels in the sample before it’s tested. Similarly, while green and amber containers may provide some protection against light, they are not specifically designed for optimal bilirubin preservation like dark containers are. Therefore, choosing a dark container ensures that the bilirubin levels remain reliable for diagnostic evaluation.
