6240 RCP
Collection Medium:
Clear top tube
5 mL
Rejection Criteria:
Test cannot be added to a urine sample previously utilized for urinalysis testing (LAB1160, LAB1164, LAB8379).
Testing Schedule:
24 hrs/day, 7 days a week, including holidays.
Turn Around Time:
30 minutes
Reference Range:
Positive = pregnant; negative = not pregnant (or <2 weeks) Positive if over 20 mIU/mL
This assay may be significantly impacted by high-dose biotin (>5 mg dose) taken within previous 12 hours. High concentrations of biotin may lead to falsely decreased results. These concentrations may be found in patients taking over-the-counter supplements with biotin content much higher than nutritional requirements for biotin. Specimens should not be collected until at least 12 hours after the last dose.

Cutoff is 20 mIU/mL HCG in urine. If results are unexpectedly positive, consider testing using quantitative serum HCG assay. False negative results may occur when the levels of HCG are slightly below the cutoff. When pregnancy is still suspected, a repeat urine HCG 48 hours later or a quantitative serum HCG should be considered. Results should always be assessed in conjunction with the patient's medical history, clinical examination and other findings.
