Why Were Some Of My Results Reported As Insufficient Sample?

For most tests, when your sample is received by the laboratory it is centrifuged to remove the cells and isolate the serum (fluid component) of your blood. 

The volume of serum that results varies, based on the total blood collected and between individuals, and it is used for the analysis of each of your tests individually. 

As these are requested in alphabetical order, and also in different panels, there may be sufficient serum available for the first tests, but unfortunately not for your complete test panel to complete.

This is an infrequent occurrence, as our tests are calibrated to work with the volumes provided in a self collected sample.

However to help minimise the chance of insufficient sample, you may wish to slightly overfill your sample tubes if possible.
