General Sample Storage
All samples collected or obtained, except for a few that require other specific instructions as indicated in the sample types, are left at room temperature in the clinics while awaiting pick-up by the despatchers of Parkway Laboratory Services. For specimen pick-up services, please call our Client Support hotline at 6278 9188.
Do not keep the samples overnight in the clinics as these samples may give erroneous and misleading analytical results to some tests reported. Examples are falsely elevated potassium level, falsely low glucose result, etc.
Please note that blood/urine specimens CANNOT be kept after 12 hours for tests such as Acid Phosphatase, Calcium, CMV DNA, Electrolytes, Glucose, HCV RNAQ, Phosphate, Urine Culture and Urine FEME.
