How much hCG does first response 6 days detect?

One kit, the First Response Early Result Pregnancy Test, emerged as the most reliable and sensitive test. "It detected hCG at concentrations as low as 6.5 mIU/ml (thousandths of an International Unit per milliliter) – that's almost sensitive enough to detect any pregnancy soon after implantation," CR wrote.

How quickly should hCG rise?

In the first four weeks of a viable pregnancy, hCG levels will typically double about every two to three days. After six weeks, the levels will double about every 96 hours. So, if your baseline level is higher than 5 mIU/mL, your doctor may order a repeat test a couple days later to see if the number doubles.

How much hCG do you have after implantation?

After implantation, pregnancy hormone levels should start to rapidly increase, doubling every couple days. hCG levels at 5 weeks should be about 19 to 7,340 mIU/mL. As you can see, it's a big increase from week 4!
