22678 HCG, Tumor Marker, Serum

HCG, Tumor Marker, Serum
Test Code: HCG-TM
Specimen Requirements
Fasting Required Specimen Type Preferred Container/Tube Acceptable Container/Tube Specimen Volume Specimen Minimum Volume
(allows for 1 repeat)		 Pediatric Minimum Volume
(no repeat)
No​ Serum or Plasma​ Serum Separator Tube (SST) Red Top Tube (RTT),​Lithium-heparin Plasma Separator Tube (PST), Sodium-heparin Green Top Tube (GTT)​ 0.5 mL​ 0.4 mL​ 0.3 mL​
Specimen Stability Information
Specimen Type Temperature Time
Serum/Plasma​ ​ Ambient​ 8 hours​
Refrigerated​ 7 days​
Frozen​ >7 days​
Interference
Human Anti-Murine Antibodies (HAMA) may develop leading to test interference in patients receiving murine-based agents for chemotherapy or tumor-imaging studies. Fluorescein will interfere; specimens should not be drawn for 48 hours following fluorescein angiography for diabetic retinopathy.​
Performing Laboratory Information
Performing Location Day(s) Test Performed Analytical Time Methodology/Instrumentation
Marshfield​ Monday through Sunday​ Less than 2 hours​ Two-Site Sandwich Assay, BCI DxI​
Test Information
Test measures native intact-HCG and free beta-HCG subunits (Total beta-HCG). Method is identical to that used for quantitative serum pregnancy testing (HCG-Pregnancy). CSF cannot be tested by this method and should be sent to Mayo Medical Laboratories (CSF must be frozen).​
Reference Range Information
Performing Location Reference Range
Marshfield​ Non-pregnant females: 0-6 mIU/mL
Males: 0-2 mIU/mL​
Interpretation
Persistent elevations (10-100 mIU/mL) of HCG in females for weeks or months could reflect an interfering substance. HCG assessment in urine or with an alternative serum assay (contact Lab) is recommended in these situations.​
