HE4, Ovarian Cancer Monitoring

Last Modified: 6/27/2016 1:26:42 PM


Specimen Requirements:

1.0 mL Serum from a Red Top Tube in a Plastic Vial

Collection Instructions: Sample collected must be allowed to clot for at least 30 minutes but no longer than 1 hour
Minimum Volume: 0.3 mL Serum
Transport & Storage: Temperature/Stability: 48 hours Ambient
72 hours Refrigerated
28 days Frozen
Rejection Criteria: Gross hemolysis • Lipemia • Icteric specimens • Presence of fibrin, RBCs or other particulate matter • Obvious microbial contamination
Reference Range:
Female Premenopausal ≤70 pmol/L
Female Postmenopausal ≤140 pmol/L
Test Comments: Limitations: A clinical study indicated that serial HE4 levels correlated with clinical status (progression vs. no progression) in 70% (247/354) of the study participants.
Methodology: Chemiluminescent Microparticle Immunoassay (CMIA)
Clinical Significance: The percentage increase in HE4 values has been used as an aid in monitoring recurrence or progressive disease in patients with invasive epithelial ovarian cancer. Currently there is no clinically accepted cut-off for use in monitoring cancer progression in epithelial ovarian cancer subjects with this assay. Serial testing for patient HE4 assay values should be used in conjunction with methods used for monitoring ovarian cancer.
Custom Panel: No
