Urine test vs blood test for pregnancy
Common Questions and Answers about Urine test vs blood test for pregnancy
urine-test
You likely had an evap line on your first test. That's why they say to discard a pregnancy test after so many minutes because an evap line can appear and look positive when it's not. The digitals are a lot more accurate, and if it's saying "not pregnant" then you're likely either too early to test or not pregnant at all.
If you got a beta HCG test it should tell you what level your blood comes back as vs yes or no for pregnancy. Anything higher then 5 is considered pregnant. Most pregnancy tests cant detect pregnancy until your reach a level of 25 or above. Although first response has been proven to detect it as early as 12.
ve heard that diuretic medications can cause a false negative pregnancy test. I can see how this would interfere with a urine test if the diuretic is diluting the urine, but can it also cause lower levels of hCG to show up in the blood?
Also, another awful thought is if levels of hCG are too low to detect in the blood 25 days after conception could that mean miscarriage or something wrong with a pregnancy?
Is it possible to have a negative urine pregnancy test and then have a positive blood test? Next fri. I am to go in and do a urine test and a blood test. They said I would get the urine test right away but the blood test they would have to call me later on. Just wondering if I get a negative urine test is there still hope for pregnancy? Also they transferred 2 embryos so would you be able to tell if there are still 2 if the HCG level is high?
Hello,
Blood pregnancy tests are fairly accurate and more specific than urine for pregnancy tests. if it has come out negative then chances of pregnancy are less.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
These symptoms take up almost 1-2 weeks to appear after a missed period. Take up pregnancy test. Urine pregnancy test is a very sensitive test for diagnosing pregnancy if done correctly. It detects the presence of beta hcg in urine. This test can be taken up 2-3 days after a missed period. If pregnancy test is negative other causes of your symptoms could be hormonal imbalances etc.This is merely an advice and not a substitute for clinical examination.
I've only had my blood drawn once for them to test if I have anything at the beginning of the pregnancy and than when I had to do the first and second glucose test and I'm 35 weeks and 3 days
Hello,
If you are apprehensive regarding the status of your pregnancy you can get it checked. Most home pregnancy tests that check urine beta-HCG are sensitive to 20-25 mIU/ml of HCG. The test can be positive anywhere from about 2-3 days prior to a missed menses to 4-5 days after, but usually it should be done 7-10 days past your missed period.
Otherwise you can get a serum HCG also done which is more specific than urine pregnancy test.
Unfortunately people often read pregnancy tests wrong. So a blood or urine test by your doctor would probably be the best way to go. Or get a different pregnancy test that is easier to read.
That being said, no matter how faint a line (unless its to the point of being an imaginary line) it tends to mean a person is pregnant. Testing your urine first thing in the morning may produce a darker line.
Good luck!
I had a miscarriage on 2/22 and my HCG level is still at 10 as of April 8. I did a urine test at the dr's office same day on April 8 with negative result. Today, 4/13 I did a home pregnancy test and it's positive. What's this mean? is there a difference from the urine test given at the lab and urine test at home?
A positive is a positive. I would wait or day or two and take another test with first morning urine but I would say you're pregnant.
A test at this point should be more than accurate. Get another one (pink dye is recommended) and take it with first morning urine. If this too is negative, make an appointment with your doctor and have blood testing done.
@kaylee..no I didnt hv sex for about 2 months now ;) I read it somewhere that for females few rbcs in urine are normal..should be concerned if its nly higher than 3-4..but im worrying about the presenc of organism in urine..in the report they hvnt indicated any value..just a plus sign..so should I get a urine culture done to get treated?
You can do a home test all you want. Just remember that if your doctor scheduled you for a blood test on the 11th, a urine-based home test on the 2nd isn't likely to register any hCG ... if the doctor thought you'd get a reliable result on the 2nd, he would have scheduled your blood test on the 2nd.
You pm'd me that your doctor was adamant that you can not get pregnant because you have not had sex. Are you actually asking if you are pregnant again?
You get results immediately from both of those if they were for pregnancy. As in right there and then.
