What effect does a short sample have when collecting in a serum clot tube?

Causes contamination
Leads to inaccurate results
Has no effect
Requires resampling

The correct answer is: Has no effect

A short sample in a serum clot tube does not have any effect as it will still be able to clot and separate the serum from the blood cells. However, if the sample is too short, it may not provide enough volume for all necessary tests to be performed, which can lead to inaccurate results. Additionally, a short sample may also require resampling, which can be inconvenient for the patient. Therefore, while it does not cause contamination or affect the clotting process, a short sample may have other negative consequences in terms of obtaining accurate and sufficient results.
