However, if you do a test and you get the faintest coloured line in the 'pregnancy' test-strip/assay area on the test, then HCG has definitely been detected. The test line (T) is not visible. This is when, on average, the hCG level in a woman’s urine reaches the 20 mIU/ml/hCG threshold. One reason why hCG levels may be low could be because you're still very early into your pregnancy. Built-in procedural controls. It is very very common for women to have pregnancy tests come with different strengths of lines. Try testing after a week or so, and see if you get a darker line. It takes a few days for the hCG production of twins to outpace the hCG. Maybe the reason its faint because its early to test and the higher the hcg level the darker the strip. It is changeable, so how do you know whether your hCG level is normal and you are going to have pregnancy problem. At 8dpt my levels were 109.
