Specimen Requirements

Specimen Preparation

All laboratory quality begins at the point of specimen collection and relies on timely procurement and adequate sample volumes. Specific sample requirements for our tests are listed below. For your convenience, a downloadable PDF is available as well.

Ship specimens to:

siParadigm
25 Riverside Drive Ste. 2

  • Patient Name (last name, first name or initial)
  • Date of Birth (DOB) (month/date/year)
  • Barcode Label - may be used if the barcode matches the unique identifiers on the accompanying requisition.
