Low Test Sensitivity

Different tests detect hCG at different levels, from 20MIU to 100MIU or more. 20MIU will display a faint line when hCG levels are at 20 MIU, while less sensitive tests will display a negative result. At 50 MIU levels, a 20 MIU test will show a stronger color band while a 50 MIU test will show a very faint band.

Can I put my mind at ease? My tests are strong lines in all my HPT strips from 11dpt onwards...
