A phlebotomist is collecting a lactic acid sample that will be transported to an outside laboratory. Which of the following actions should the phlebotomist take when handling the specimen?

Rationale

Chill the sample.

Lactic acid samples require refrigeration to maintain stability and prevent degradation during transport to the outside laboratory.

A (Protect the sample from light.) YOUR ANSWER

While light protection is crucial for some lab tests, lactic acid samples primarily necessitate temperature control for preservation. Shielding from light is not a standard requirement for lactic acid sample handling.

B (Chill the sample.) CORRECT

Chilling the lactic acid sample is essential to maintain its integrity and prevent alterations in composition that could occur at higher temperatures. Refrigeration slows down enzymatic reactions that could otherwise degrade the sample.

C (Transport the sample at 37°C (98.6°F).) YOUR ANSWER

Transporting the lactic acid sample at body temperature is not recommended, as this could lead to rapid degradation of the sample. Refrigeration, rather than heating, is the appropriate method to preserve lactic acid stability.

D (Freeze the sample.) YOUR ANSWER

Freezing the lactic acid sample is excessive and can potentially alter its composition due to the formation of ice crystals. Refrigeration, which is milder than freezing, is the preferred method for maintaining sample quality.

Conclusion

For lactic acid samples being transported to an outside laboratory, the phlebotomist should prioritize chilling the sample to ensure its stability and integrity. This practice helps prevent enzymatic degradation and maintains the sample's composition for accurate testing at the destination laboratory. Temperature control is critical in preserving the quality of lactic acid samples during transit.
