How many days past ovulation will a blood test show pregnancy?

How many days past ovulation will a blood test show pregnancy?

About two weeks: The blood test should be most accurate about 14 days after ovulation. It's possible to get a positive blood or urine pregnancy test earlier than this. But it's not as reliable as the 'two week wait'. A HCG 'trigger shot' can give you a false positive pregnancy test if you test too early, as well. ...Read more

If i was pregnant would it show in a ovulation blood test?

What should my levels be for a pregnancy blood test to show im pregnant too them?

What should my levels be for a pregnancy blood test to show im pregnant too them?

Testing: You are asking the wrong question. HCG increases daily after a viable pregnancy is old enough to be big enough to have blood and chemicals. That transition occurs at about ten days post conception. It also corresponds with the time a period is due and it stops the period leading to a missed period and the first real symptom of early pregnancy. That is the sign to look for to know when to test. ...Read more

Good night i have a friend she is about 9week pregnant but they cant fine a heartbeat and she do a blood test and it show she is still pregnant?

Not 9 weeks?: You should see a heart-beat at 9 weeks; however, its possible that your friend is really less than 9 weeks. Also, a single blood test won't clarify the situation. She needs two blood tests 48 hours apart to know if the the pregnancy hormone level is going up or down. There are gray areas where its hard to tell. In these cases, the ultrasound and bloodwork is repeated at another time. ...Read more

Can blood test show if I am pregnant. If urine test showed negative?

Can blood test show if I am pregnant. If urine test showed negative?

Possibly.: These tests are good, but like all tests, can have variations. Blood tests can detect this shortly after implantation as well as urine tests that are sensitive, but less sensitive blood and urine tests need 3-4 more days to become positive. No two people are alike either, so that can cause variations also. Time and a specific quantitative test can best confirm this, so see your dr. To be sure. ...Read more

Ectopic?: Sounds confusing - no blood test can date the pregnancy, only ultrasound. Seek medical care with serial blood HCG and transvaginal sonograms to exclude the life-threatening diagnosis of ectopic pregnancy. Take Folic Acid 1-5 mg daily and good luck! ...Read more

Insensitive test: Every commercial pregnancy test as a threshold of HCG present in your urine that will convert the test to positive. It is not zero. Thus blood pregnancy tests are more accurate as ANY HCG can be detected no matter how small. ...Read more
