If a test is declined, the specimen will be held for a reasonable period (usually 3 weeks but dependent on the stability of the sample). Medical practitioners seeking approval for a declined test should email the on-call Chemical Pathologist, giving the patient's name and NHI number and the clinical justification for the test. If unable to email, call the on-call Chemical Pathologist via Lablink and identify yourself as a doctor.
