Clients may call the Laboratory Client Service Center at (248) 888-2580, to request that additional tests be performed on a previously submitted sample. Please fill out Add-on Test Form with the patient's name, account number (if available) or Social Security number, the date the specimen(s) were originally submitted to the Laboratory, the additional test(s) to be performed, and any additional ICD-9 diagnosis codes. Most blood specimens, body fluids, and twenty-four hour urine specimens are retained for seven days. Random urine specimens are discarded after twenty-four hours. Stool specimens are discarded after forty-eight hours. Some specimens may not be suitable for testing at a later time and some tests may not be accurate when performed on a stored specimen; therefore, it is important that the laboratory is notified as soon as possible of any additional test requests.
CLIA 88 Regulations require a written confirmation for any verbal request(s). A "Written Verification of Verbal Orders or Incomplete Requisition" form will be sent to the physician for an authorized signature. This form must be returned to the Laboratory within twenty-four hours.
