Beta hcg result <.100 means pregnant or not?

Hard to say: Bhcg &gt;5mIU/mL is indicative of a positive test, however whether or not you have a successful pregnancy depends on the trend of the Hcg. If a repeated test in two days shows an increasing number (doubling) then this could be a normal pregnancy, otherwise it might be abnormal/miscarrying/ectopic, in which case you should be evaluated. See an emergency room for any severe pain/bleeding. Good luck.

Depends on lab: It depends on the lab standardization on test reporting results. Some labs report negative tests as less than 100 instead of zero on quantitative HCG's.
