Hello,

Thanks for writing to us.

An underactive thyroid cannot cause a false negative pregnancy test.

If you are pregnant, the urine pregnancy test is upto 97 % reliable in diagnosing a pregnancy.

Of course, a blood B HCG test, or a pelvic ultrasound, is more reliable.

Take care.

So the hormones the thyroid produces is not the same as the pregnancy hormone?
 
 
Answered by Dr. Aarti Abraham 1 hour later
It is not the same.
Thyroid hormone TSH and pregnancy hormone B HCG are similar, not the same.
WIth underactive thyroid, the TSH is raised ( it is opposite effect ), so if at all, the kit would cause false positive result, however even that does not happen, as the kit is specific for B HCG.
In short, an underactive thyroid does NOT affect your pregnancy test result.
