A serum hCG will be positive for pregnancy at 25mIU/ml, the urine test, although just as accurate needs a stronger concentration of 50mIU/ml to 100mIU/ml depending on the brand - this means the serum (blood) test will test positive 2 to 3 days sooner than urine.

Can you test positive with a urine pregnancy test and negative on the blood?
Yes, it is possible to have a positive result on a urine pregnancy test and a negative result on a blood pregnancy test. This could be due to differences in the sensitivity of the tests or the timing of the tests relative to the hormone levels in the body. It is recommended to confirm with a healthcare provider for further evaluation.
Is it possible to be 10 weeks pregnant and get a negative urine test if you do?
Some women do not get a positive pregnancy test will late in their pregnancy , if even. A blood pregnancy test is the best way to go.
If i have got a coil the hpt test is positive but the doctors blood test is negative and i have all the symptoms of pregnancy can i still be pregnant?
sometime hpt gives false positive... if you took a doctor's urine pregnancy test and came back negative then ask for a blood test--a blood test will tell you if you are pregnant or not- even if you have low hcg in your urine-and yes you could still pregnant with all the symptoms---best of health
Use home pregnancy test and the result are positive but the blood test result is negative am i pregnant?
i would try another home test to be sure. the hormones that are used to identify pregnancy can be found sooner in the blood than in the urine.

Yes. I don't know how but it can happen. I cannot use the urine preg. tests , I have to have the serum and then it has to be the quantitate not the yes or no one.
If symptoms of a UTI are present including white blood cells in urine but no infection is found can this be an early sign of pregnancy?
No. Signs of pregnancy are absent period and positive pregnancy test. White blood cells in urine and painful urination are not signs of pregnancy.
Why would a urine test come out positive before taking and negative after taking antibiotics for a bladder infection when you are on Mircette Birth Control and started your period a week ago?
Bladder infections can spread into your kidneys and then into the blodd stream so they were probably checking to see how far it had progressed. I dont know if you understood my question, i know why they took the urine and blood samples. But i dont understand why a pregnancy urine test would say positive 3 times, pregnancy blood test say negative twice, and then another urine test done 6 hrs after being administered antibiotics come out negative. What was with that first urine test saying positive?
Can you get a negative urine pregnancy test even if a blood test comes back positive?
No, a urine pregnancy test measures the same hormone (hCG) as a blood test, so they should typically give consistent results. If a blood test is positive, a urine test should also show a positive result.
Are you pregnant if a home pregnancy test came back positive and a laboratory urine test was inconclusive and why would they be different?
Hello there. Yes you may very well be pregnant. A pregnancy test will only turn positive once HCG has been found in your urine. BUT there needs to be ENOUGH HCG in your urine to make a positive test result. Depending on the pregnancy test, they usually look for 5MIU - 50MIU. If you had 49MIU of HCG in your urine and did a test that looks for 50MIU it would be negative. The same thing applies to the Labatory urine pregnancy test. When they did the test you probably didn't have enough HCG in your urine to give you a positive. You need to have a blood test. Urine tests are NOT reliable and give negative results when women are indeed pregnant. See your doctor for a Quantitative Beta HCG pregnancy test. Good luck.
Is it possible to get a positive result with first morning urine but get a negative result with urine after that?
Yes, the urine in the morning has high quanties of the hormones needed to produce a positive pregnancy test. If you are very early on in your pregnancy, it could show up negative later in the day, either wait a bit longer - a few more weeks, before taking another test, or even better go to the doctors and he will do a blood test! Yes, that is why the instructions tell you to test with the first urine you pass in the morning. The test is 99% accurate if positive with the first urine of the day.
I got 3 faint positive urine tests but a negative hcg blood test why and can it be wrong?
On rare occasions you can encounter a false positive due to improper testing, expired pregnancy tests, rare medical conditions such as certain types of cancer, evaporation lines, a recent pregnancy or a chemical pregnancy.
I have had three positive urine pregnancy tests and a negative blood test which is corrct?
I had the same thing happen to me. I took several home pregnancy tests that came back positive. I went to the doctor they did a blood test and it came back as negative. They sent me to hospital to do a 48 hour hormone test and determined I was miscarraging the baby. You should ask your doctor if this is hapening to you. Hope this helps.
