How to prepare samples

The quality of laboratory results depends greatly on proper collection and handling of specimens. Specific sample requirements for each test are listed in the Test Center. For your convenience, general guidelines are available in the sidebar for you to download.

Specimen labels

All specimens should be labeled at the time of collection with at least two patient identifiers.

  1. The patient's name (last name, first name or initial)
  2. The second patient identifier may be one of the following:
  • Date of birth (month/date/year)
  • A barcode label can be used if the barcode matches the unique identifiers on the printed requisition


Specimens must be accompanied by a paper requisition, prepared either by hand or printed from an EMR system. The requisition should contain the following information:

  • Client information: Client’s Name / Facility’s Location – Address / Ordering Physician’s Name
  • Patient demographics: Full Name / Address / Gender / Date of Birth
  • Clinical data: Clinical information / ICD-9 Code – Diagnosis
  • Billing information - check appropriate billing method under “Bill To” and include: Insurance Card Information (copy) / Medicare/Medicaid numbers / Copy of Patient’s face sheet (demographics) is also acceptable
  • Specimen Data: Test(s) requested / Date of specimen collection / Source and type of specimen and time of collection / Submit all specimens within a series together in one specimen shipper.

Specimen rejection criteria

Specimens will be rejected for the following reasons:

  • Specimen is not properly labeled with required patient identifiers
  • The information on the requisition and the specimen sent do not match
  • Specimen is received without a requisition
  • Inadequate Specimen – specimen volume requirements are not met or the condition of the specimen is not appropriate for testing
