How should underfilled tubes be handled?

Explanation:
Tubes are designed with a precise amount of additive so the blood-to-additive ratio stays correct. When a tube is underfilled, that ratio is off, which can skew test results and, for some tubes, even cause clotting or improper mixing. For example, a blue-top citrate tube requires a 9:1 blood-to-anticoagulant ratio; if it’s underfilled, coagulation tests can become falsely altered. The proper approach is to avoid underfilling by filling to the manufacturer’s specified volume or recollecting a fresh draw to meet that volume. Using the tube as-is, documenting it as partial, or diluting with saline can invalidate results and is not appropriate practice.
