After collecting a bilirubin test, a phlebotomist should take which of the following actions post-venipuncture to ensure an accurate test result?

Rationale

The specimen should be kept away from direct light.

After collecting a bilirubin test, it is crucial for the phlebotomist to protect the specimen from direct light exposure. Bilirubin, a light-sensitive compound, can degrade when exposed to light, leading to inaccurate test results if not properly shielded.

A (The specimen should be chilled.) YOUR ANSWER

Chilling the specimen is not necessary for maintaining the integrity of a bilirubin test. While some tests require specific temperature control, bilirubin testing does not typically necessitate chilling to ensure accurate results.

B (The specimen should be kept away from direct light.) CORRECT

Correct. Direct light exposure can cause bilirubin degradation, affecting the accuracy of the test results. Shielding the specimen from light helps preserve the integrity of the bilirubin sample and ensures reliable testing outcomes.

C (The specimen should be spun down and frozen.) YOUR ANSWER

Spinning down and freezing the specimen is not a standard post-venipuncture procedure for bilirubin testing. These steps are generally unnecessary and could complicate the testing process without providing any significant benefit for bilirubin analysis.

D (The specimen should be placed on a warming block.) YOUR ANSWER

Using a warming block is not recommended after collecting a bilirubin test specimen. Warming blocks are typically employed for certain tests that require specific sample temperatures, which is not the case for bilirubin testing.

Conclusion

To ensure an accurate bilirubin test result post-venipuncture, it is essential for the phlebotomist to protect the specimen from direct light exposure. This precaution helps maintain the stability of bilirubin in the sample, ultimately leading to reliable test outcomes.
