What should be done when a blood sample is rejected for being QNS (Quantity Not Sufficient)?

When a blood sample is rejected due to being labeled as QNS (Quantity Not Sufficient), the appropriate action is to collect another sample with sufficient quantity. This is essential because many laboratory tests require a specific volume of blood to ensure accurate results. A sample that does not meet these volume requirements cannot be analyzed reliably, which compromises the quality of patient care if results are based on inadequate data.

Collecting a new sample allows for a proper analysis to be conducted and ensures that the necessary diagnostic information can be obtained. This step is critical in maintaining the integrity of the medical results and facilitating effective treatment decisions based on accurate clinical information.
