How Sensitive Is The Doctors Urine Test

Hi all, I'm reading a lot of pregnancy test confusions here, and mine is no different. I am 33 days out from my last period (and have a cycle of 28-30 days) and did a home test yesterday (First Response) and got a faint line. I rushed off to the doctor to get it confirmed, meaning they made me do another urine test. It came out NEGATIVE. I was bummed, but suspicious, so I did another hometest yesterday afternoon, and it came out POSITIVE again. So I did another one this morning, and again POSITIVE. Now... My question is if anyone knows how sensitive the home tests are compared to the doctors urine test. I read somewhere that First Response detects 12.5 mIU of hCG, and when I asked the doctors lab what they used, they didn't know! (great!) Any thoughts on my situation I can add that I have a slight "burning" feeling in my uterus, something I had with my first baby. But then there were no test confusion either!! :-(

I am sure every doctor's office uses a different variety. I had mixed HPT results at home and a BFN urine test at the doctor's office. The best thing to do is request a blood test. That way you will know for sure! My blood test was a BFP, so the urine tests at the doctor's might not be the most sensitive. Good luck!

I'm sorry for the ignorance but do you mind explaining the difference between the two? Mixed HPT and BFN. I certainly will re-test at the doctors office on Monday. My mind "knows" I'm pregnant but I really want to know on paper too!

she means that her home pregnancy tests had mixed results (some postive, some negative) and the doctors urine test was negative (bfn means big fat negative)

I have only heard of one HPT picking up HCG levels of 10 and im sure the name wasent first response. I do know the dollar tree tests pick up low HCG and I think the drs test pick up 50 HCG, not too sensitive. i would definatly test again witht he dr on monday.

Hi, when i got pregnant in septembet 2006, i had positive HPT at home , i tested using 8 of them and all came back +, when i went to hte doctor, it was nigative. so, he sent me to a blood test that confirmed my pregnancy at that time. so, the doctors tests are not reliable if you are earlly in your pregnancy . good luck

I agree, a blood test would be the best thing. A urine test is just a urine test even if done by a dr. office. But if you add a few more days before going back in to test then you should get your bfp with the dr. test b/c as more time goes by the higher hcg in your system.

Hi everyone, I just wanted to thank everyone, and give you a quick update. I went to the doctor today and YES, it sure was positive! So I guess it's true, the First Response test was much more sensitive than the doctors! Thanks again for your replies!
