Ordering Information


Request for Testing (RFT)

Testing is requested via a Request for Testing Form. Forms may be ordered through the Business office at 425-656-3019. The following information must be completed on the RFT to avoid delay in testing:

  • Patient Identification (must match information on specimen).
  • Physician or authorized individual ordering test.
  • Draw date and time.
  • Whether the sample was frozen if only a serum or plasma aliquot is submitted.
  • To whom should the report be sent.
  • Include a contact name and phone number for someone who can answer questions concerning the order.

Labeling Samples

All samples must be properly labeled and information must agree with the identification on the RFT.

  • If a specimen is identified by name, there must also be a numeric identifier which may include Hospital number, birth date, or other coded identifier
  • If only a numeric identifier is used (with no name), the number must be a Hospital number, or coded identifier. A birth date is not acceptable in this circumstance.
  • A draw date should be on the sample but the sample will still be accepted if the draw information is on the RFT.
