Dear Cathy

It is not possible if you are using the urinary LH detection kits. However, if you are relying on the cervical or mucous tests then certainly the high oestrogen levels in pregnancy may result in false positive ovulatory tests.

OPK's as HPT's:
using an ovulation test to confirm pregnancy

Overall-- yes, it can be done. Ovulation predictor tests (known as OPK's because they are normally sold in a set of tests known as a "kit," thus the K) will show a positive result when a woman is pregnant, as well as when she's ovulating.

OPK's detect LH (luteinizing hormone) which is the hormone associated with ovulation. Pregnancy tests detect hCG, the hormone associated with pregnancy. LH and hCG are, at a molecular level, nearly identical.

I think it is highly unlkely, Ovulation tests are designed to detect lutenising hormone, and pregnany tests detech hCG.

Yes, an ovulation test can actually be used as a pregnancy test and will show positive if you are pregnant.
