Does anyone know why a pregnancy would only show on a blood test and not a urine test?

Question

Also, is it usual to feel really tired and exhausted all the time when you are pregnant and any suggestions for nausea?

Answer 1

a blood test can detect pregnancy almost to the conception date there more sensitive good luck oh try mints before getting up and take naps as many as you can good luck

Answer 2

If you take a blood test that is 100% accurate and it will show however, taking a home pregnancy test is also accurate not like a blood test it is about 99.9% or 98.9%. I have always got accurate results using the home pregnancy test.

If you are not taking the test correctly, there is a possibilty that you wont be able to see accurate results but if you take the test correctly it should be positive or negative.

It is common to feel tired and exhausted because your body is going through changes and that's going to happen. Also, the nausea is also caused by the pregnancy... The good thing is it will go away when you reach your second trimester however, not all women do. I was so sick during my first trimester I was thinking of having an abortion at the time because I could not take it. But I hung in there and now that I am 35 weeks, I feel so much better.... Good Luck to you....

You urine just may not have the levels needed for the test to read correctly, but a blood test is the best way to go, it's certain. You will be tired on and off during your pregnancy, there is another person using your energy! Take your vitamins the doctor gave you, eat right and get lots of rest. Sometimes you will have nothing but energy. Nausea will be at it's worst during the 1st trimester, sometimes throughout the entire 40 weeks. Crackers, toast, bananas, rice all work for it. If it gets worse, mention it to your OB, there is something they can give to decrease it. Good luck and congrats.

Answer 4

vitamin b6 25ml three times a day. It will totally take care of the nausia. Eat crackers before you even sit up in bed. Avoid your prenatal until you have food in your stoamch.

Yes, you will feel tired through out pregnancy, worst of all in the begining, less in the middle, and tired again at the end when you're heavy.

A urine test requires more consentrated amounts of the human growth hormone. Blood tests can detect a much smaller amount. In some cases it blood test will show when a urine test does not, especially if the mother is not late for her period, or doesnt produce a lot of the hormone needed to trigger the tests.

Have fun, its a great ride.

Answer 5

Yes sometimes you will be really really tired like you want to sleep until you die but sometimes you will be so energetic that you can't go to sleep at night. it all has to do with your baby growing and taking all of your power but if you eat a well balanced meal and drink lots of water along with juice and milk then you should be OK. please stay away from sodas they have too much sugar and sodium for the baby. it takes away nutrients also. maybe there wasn't enough of the hormone that detects the urine test in your urine but it doesn't matter how much or little is in your blood they will always be right so that's probably why. GOOD LUCK!

Answer 6

If a blood test is positive and a urine test is negative, it means the hcg is too dilute to be detected by a urine test. Blood tests are more sensitive.

Being exhaused is a common symptom of pregnancy.

Answer 7

Blood can detect the hormone at level 30 however most urine tests do not detect that soon.

As for as nausea there are these altoids that are ginger flavored that really help me.

Answer 8

Blood test can pick up hormone traces easier. It is normal to be tired at least during the first trimester. For nausea, try ginger tablets. You can find it in the vitamin section, works great also for motion sickness.

Answer 9

A blood test is the most accurate way to tell if you are pregnant, since urine can tend to give you false results.

Answer 10

Not enough HCG in urine, and blood test can pick it up quicker.
