Sample Volumes and Type
For specific details of sample volume and type requirements see test listings. If a short sample is obtained then please contact the laboratory to discuss test options.

If further tests are required on a patient in the light of earlier results, it may be possbile to save the inconvenience of a repeat venesection for the patient by contacting the laboratory and arranging further tests on the stored serum.
