my friend has got to have a blood test to see if she is pregnant but was wondering what the earliest is that a blood test will pick it up from.
Her home tests are all saying negative at min but she is 5 weeks late and has not been taking any contraception since mid jan.

The most sensitive of home pregnancy tests have a range of 20-50ml hcg sensitivity. The more sensitive the test, the sooner it would pick up pregnancy. There are two types of blood tests: quantitative and qualitative. A qualitative blood test would show the same result as a home pregnancy test - either a yes or no. However, a quantitative, or beta, hcg test will produce an actual number to show where the hcg levels are at. The body is considered pregnant with a level above 5, and the rate normally doubles every 2-3 days. With that said, typically a blood test will show a positive a few days before a home pregnancy test would. It would take a few days after implantation for this result to occur. Typically implantation occurs 7-10 days after conception. Hope this helps.

A blood test is very sensitive and very accurate and can detect pregnancy from a few days after conception. If she is pregnant then at 5 weeks it will definately confirm it. If she is not it is quite safe to say she is not from a blood test and that the cause of her missed period may be something other than pregnancy, but her doctor should advise from here on.

Both tests should pick up pregnancy from 1 week after a missed period. Having a blood test will not hurt anything but home tests are more likely to give a false positive than a false negative.

No idea, but a classical acupuncturist can pick it up really early. Think i was only 6 weeks or so when he confirmed i was pregnant through pulse diagnosis. Not sure on a TCM one though (what is available on the NHS). They have chosen to forget most of the old ways in favour of pharmaceutical greed

As far as blood goes, not far at all. 5 weeks along, it certainly can be picked up in the blood. Her hormones may not be strong enough in her urine.

A blood test should be very accurate right now.
