When testing for pregnancy after a medical termination of pregnancy (MTOP), it’s important to understand the difference between a Low-Sensitivity Urine Pregnancy (LSUP) test and a High-Sensitivity Urine Pregnancy (HSUP) test.
What is an LSUP?
A Low-Sensitivity Urine Pregnancy (LSUP) test detects hCG levels above 1000 IU/L. This type of test is specifically designed to assess whether hCG levels have dropped significantly after a medical abortion. If an LSUP test is negative, it confirms that hCG has fallen below the threshold, indicating that the abortion was successful.
What is an HSUP?
A High-Sensitivity Urine Pregnancy (HSUP) test, like those found in pharmacies, detects hCG levels as low as 25 IU/L. Because hCG can remain in the body for several weeks after an abortion, a store-bought HSUP test may still return a positive result for up to four weeks post-MTOP, even if the pregnancy has ended.
Why Does This Matter?
- If an HSUP test is positive, it does not necessarily mean you are still pregnant, as residual hCG can linger.
- An LSUP test provides a clearer answer by determining whether hCG has dropped below the level where an ongoing pregnancy would be expected.
- If an LSUP test is still positive, further assessment may be needed to rule out an ongoing pregnancy or retained pregnancy tissue.
Key Takeaways
✔️ LSUP detects hCG above 1000 IU/L, making it more reliable for post-MTOP follow-up.
✔️ HSUP detects hCG as low as 25 IU/L, which can remain positive for up to 4 weeks post-abortion.
✔️ If you have a positive HSUP test after MTOP, an LSUP test or follow-up with a healthcare provider can give more clarity.
