@BellaDee:  Hi, I’m not currently TTC and I’m not 100% sure what a FRER is (pee on a stick brand?) but a blood test will always be more reliable than any other method. Besides just waiting to see what pops out in 9 months, obvs. 😉 Hope I helped!

Blood test is always going to be the most accurate. But peeing on a stick will be the most quickest to know. If you’re past the date your period is due, it’s a greater chance that it’ll be accurate. There are some women I’ve read who never test positive on a test, but are indeed pregnant.

When I went in to verify my BFP at the doctor it was a Friday, and I had been getting BFP’s on my tests at home since that Tuesday and my urine test there was NEGATIVE!  They gave me a blood test and I was pregnant but my numbers showed very early pregnancy.  So for me, the blood test was very accurate, and better than their urine test but not different than the FRER.

The blood test will always be most accurate because it detects any hcg (which indicates pregnancy).  If it’s under 5 then it’s not pregnant, 5-25 is uncertain, and over 25 is pregnant (according to my research online anyway!).  When my numbers came back that day with the negative urine test they were at 35.

I had a squinter on an frer, osom, and wondfo in the morning. Went to my doctor that afternoon and my blood hcg was 5mIU/ml. So I’d say the frer was just as sensitive as my blood test. But that really isn’t the right answer to ask as the blood test measures the exact amount of hcg in your system, so it’s not a sensitivity thinG. If you are pregnant there would be hcg in your blood, the end.

FYI, not all blood tests are created equally.  On my first pregnancy, my hpt’s were showing positive, but my first blood test said negative.  Come to find out, my OB had ordered a qualitative test and the requirements for it were 25mIU/ml!!  A beta test done 2 days later showed my number at 10mIU/ml.  Early pregnancy and ended in miscarriage.  BUT, my point is that if you are getting a blood test, make sure it’s a beta!!!
