Generally, the specimen requirements are written in a format that specifies the requested volume, storage temperature, and any special handling notes. The requested volume is an amount sufficient to allow at least two performances of the assay either singly or in duplicate. The minimum volume allows one single analysis including instrument dead volume. Storage temperature is specified as room temperature (15 – 30°C), refrigerated (2 to 10°C) or frozen (-20°C or colder). When temperature is not indicated, the sample may be stored and shipped in the most convenient manner for the client. For panels or multiple assay requests, the sample should be submitted with the physician’s priority of determination on the Test Request Form. Tests will be performed in the order of that priority. If the volume is insufficient to run all the tests requested, our Client Services department will contact the physician.
