Parathyroid Hormone-Related Peptide (PTHrP) : 0093014

Mnemonic: PTH RELPEP

Methodology: Quantitative Immunoradiometry
Performed: Wed, Thu, Sat
Reported: 2-6 days
Specimen Required: Collect: Lavender (EDTA) or pink (K2EDTA). Collect in chilled container.

Specimen Preparation: Add 0.04 cc of aprotinin per 1 mL of whole blood to collection tube immediately after collection. (Example: 3 mL EDTA tube would require 0.12 cc aprotinin. 3 x 0.04 cc = 0.12 cc aprotinin) Centrifuge and separate plasma from cells ASAP. Transfer 2 mL plasma to an ARUP Standard Transport Tube and freeze immediately. (Min: 0.5 mL)

Storage/Transport Temperature: Frozen.

Remarks: To prevent analyte degradation, aprotinin inhibitor is the required additive for this assay. Inhibitor vials are available through ARUP Client Services (ARUP Supply #16570).

Stability (collection to initiation of testing): After addition of aprotinin and separation from cells: Ambient: Unacceptable; Refrigerated: 24 hours; Frozen: 3 months
