If a test is declined, the specimen will be held for a reasonable period (usually 3 weeks but dependant on the stability of the sample). Medical practitioners seeking approval for a declined test should email the on-call Chemical Pathologist ( chemicalpathologist@adhb.govt.nz ) , 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 (09-3078995) and identify yourself as a doctor.

To assist in the reporting of Creatine kinase isoenzymes a recent creatine kinase result m ust accompany the request . If creatine kinase results are not provided LabPlus will perform these tests before completing CK isoenzyme analysis.
