The Best Pregnancy Tests
I'm a pharmacist that's TTC. This whole process made me actually pay attention to the diagnostic tests available over the counter and the accuracy of them.
These tests detect the amount of hcg in the urine and are available is various sensitivities. The range is from 5.5 int units/L to 40 int units/l. The lower the sensitivity value the more accurate and early the detection is.
Studies found that First response has a sensitivity of 5.5 with a 97% detection the day of missed period. Clear Blue was 11-22 units with 64 % detection rate on the day of missed period. Other tests had a detection rate of 54%.
I would recommend waiting till day of missed period and then using the first response kits. Hope this helps !
