Conflicting Pregnancy Test Results: What Could Be the Cause?

Question
hi

i was hoping you could help me. i have done some pregnany test,
at doctors and at home and i keep getting different results. i have
done about 10 test and 4 came out positive and four negative. i am
very confused. have you heard this before? i have a tumor on my
cervix which is benign and was wondering if this might effect the
results of the test?

Answer
Hi Barbara,

It is extremely unlikely that you would get a false positive reading.  It is more likely to get a false negative.  Are you reading the test within 3 minutes?  If you read it after 5-10 minutes, you may get a false positive.  Otherwise, the only thing I can tell you is to have your doctor send you for some bloodwork to confirm pregnancy.  That is the only sure way to know.  I don't think that the tumor would effect the results.  Good luck!
