What constitutes insufficient volume rejection and how should you respond?

Prepare for the CAMLPR Specimen Collection Competency Test. Practice with diverse question sets including multiple-choice and flashcards. Each question includes hints and explanations to help you become proficient before the exam.

Insufficient volume rejection means the collected tube cannot meet the minimum volume needed for the requested tests. That minimum volume is set because there must be enough sample to run all tests accurately and to maintain the correct additive-to-sample balance. When the tube is underfilled to that threshold, the specimen isn’t usable as-is, so the proper response is to request recollection and document the rejection reason so the lab and clinician understand why a repeat draw is needed. This preserves test accuracy and avoids invalid or biased results caused by too little material. Proceeding with an underfilled tube would risk inaccurate results, and issues like labeling or color problems require their own specific actions (recollect for proper identification, or address sample quality), rather than moving forward with an insufficient sample.
