What would cause blood in your urine? I take UTI test negative for UTI but positive for blood?

What would cause blood in your urine? I take UTI test negative for UTI but positive for blood?

Blood in urine: If a UTI is ruled out, blood can come from the kidneys, stones in the ureters, bleeding from the bladder or from glomerular diseases of the kidney. See a urologist for a diagnosis of any bleeding from the kidney or its outflow tract and bladder. If no source is found, see a nephrologist to see if the glomerulonephritis is the cause of the bleeding. Good luck. ...Read more

Repeat: I'm going to assume this is not just contamination from your monthly cycle. This will probably be repeated and maybe worked up if positive. Several percent of folks have hematuria for no reason that anyone can determine -- often it's from a particular gene, and it doesn't result in problems. ...Read more

Hormonal imbalance: Menstrual irregularities are not uncommon and anovulatory cycle is a common cause. If you miss more than two periods it would be time to see your doctor. If you do not wish to be pregnant, use contraception all the time. You may consider implanted contraceptive or an IUD.

I had a blood test when I was 8days late and a urine test and it showed negative, I am currently 1 5days late but not tested since I had bloods done?

No need to test: If your blood test was negative at 8 days after a missed period, you not likely to be pregnant. Menstrual irregularities are not uncommon and anovulatory cycle is a common cause. If you miss more than two periods it would be time to see your doctor. If you do not wish to be pregnant, use contraception all the time. You may consider implanted contraceptive or an IUD.

Still positive: Most urine pregnancy tests cannot measure HCG levels in the urine below 25 or 30 units. Also, if the urine was not your first morning urine, and therefore, wasn't concentrated, the HCG could also have been diluted to the point where it was not measurable. ...Read more

Blood test, yes: If the last episode of sex was three weeks prior to the blood test and the test was negative, the result should be reliable. You may consult this site for early signs of pregnancy.

Iv had 5 positive HPTs with faint lines, today I went to doctors and he done a test which was negative, there's also blood in my urine. Help.?

2 separate issues: The pregnancy test done at your doctor's office is more reliable. It the test was done after a missed period, you are unlikely to be pregnant.
The blood in urine needs to be investigated. That evaluation can only be done in person and you need to address it with your doctor. ...Read more

Repeat Blood Test...: You are only a few days pregnant. Urine test frequently won't turn positive until the HCG blood level is > 50. The only way to know what is going on is to repeat the blood level and see if the level is going up or down. It should increase by at least 50% in 48 hours. Its hard to wait but sometimes that is all you can do. Time is one of the best diagnostic tools there is. Best wishes! ...Read more

I had a 2day period but tested negative on blood and urine tests so should I wait and take another test because I have never had 2day periods before?

You may: If you had a period since having sex, even if it was shorter than usual, you not likely to be pregnant. There would not harm in doing the test in 7-10 days.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.

Stop Testing: Millions of dollars are wasted every year on pregnancy tests that are done too early and thus are 100% inaccurate and a waste of money and energy. Your doctor is correct. Wait till it is time to test. If the next period is over due that is when you do the first test. ...Read more

I had a routine urine test which detected blood. It was then sent off so the urine could be cultured. Can this culture come back negative if there is?

No worries: It is common to see blood present on the urinalysis test as part of a urinary tract infection. The urine culture will confirm the presence of bacteria. If the culture is negative, you GP could order further tests if you are still experiencing symptoms. ...Read more

I recently had a urine and blood test done did drink detox drink urine negative how will blood come back? Need to know

The: The blood test will likely come back positive. The detox drinks typically affects the outcome of the urine test only; and even that is not absolute although negative in your case. There is a chance that it could be negative however there is no way to know 100%, there are multiple factors involved that affect the outcome.
Best of luck. ...Read more

Its been 63 days since my last period, I did urine and blood tests but both were negative, really worried. What could be the problem?

Delayed menses: A period can be delayed for any number of reasons without it being due to pregnancy. If there is no period by 90 days, see a GYN MD if the pregnancy test is negative to get "jump started" with medication and find out why the menses was delayed to decrease your risk for endometrial hyperplasia that can go on to endometrial cancer. ...Read more

Preg symptoms. Took 4 urine tests all neg. Blood test neg as well. Would be 14 weeks. Possible to have a false negative blood test at 14 weeks?

No: The fact that you have had multiple negative pregnancy tests at 14 weeks mean you are not pregnant. Most home pregnancy tests are just as accurate as a blood test. There are many reasons for missed periods other than pregnancy. If it has been 3 months without a period see you gynecologist. ...Read more

I'm 8 weeks late. Urine test and blood test all turned up negative. Recently, I had a little bit of brown discharge coming out. What could it be?

I'm 8 weeks late. Urine test and blood test all turned up negative. Recently, I had a little bit of brown discharge coming out. What could it be?

8 weeks late: Hard to tell what the brown discharge is. If pregnancy has effectively been ruled out, it may be that you are having so called anovulation bleeding - bleeding that occurs from the overgrowth of the lining of the uterus (endometrium). It is frequently uncontrolled and may last days or even weeks. I'd go to the doc and have a full history and physical exam to begin with. ...Read more

Hospitalized 3 times in last 2 months with the symptoms from my last 2 posts here. Extensive blood, urine, & stool workup done. All tests neg. Still very sick. Will post all symptoms in next post.

Lots to consider...: Given the extensive nature of evaluation but persistent symptoms, several scenarios are possible: 1) you need further evaluation to identify missed pathology; 2) its time to take a break from testing & treat your symptoms (sounds like bad things have been ruled out already); 3) your symptoms may in part be "functional". In the latter case, please address stress, anxiety, depression. Best of luck. ...Read more

Is it possible to get a false negative on a zinc toxicity test? I had zinc, copper and lead testing done. My zinc results in blood and urine were at the high end of normal. My lead was negative but my copper results came back as low. I have all of the

Any: Any test has a risk of being a false negative or even false positve for that matter. Heavy metal toxicity/poisoning is a very difficult issue, and has been a challenge for a lot of doctors. I recommend you consult a medical toxicologist. These doctors specialize in poison and metal toxicity. If you have already done so, I suggest a second opinion by another doctor in the field.
Good luck. ...Read more

Can someone help please? My urine test for diabetes was postive. But the blood test was negative. What does that mean?

That means you had: Sugar in urine
i'll assume 'blood test' was a simple glucose test, not hga1c etc

rarely its due to a genetic defect-kidney can't reabsorb sugar filtered into urine.
Not dangerous, normal life span.

More likely is blood sugar represents 1 second in time, but glucose in urine represents sugar that was high enough to spill into urine any time since last urination- - you may have diabetes-see md. ...Read more

Loss of early: pregnancy. If the tests you described were done correctly, it suggests spontaneous loss of an early pregnancy. About 25% of early pregnancies are lost, mostly due to chromosomal defects in the embryo. Usually the only manifestation is a slightly heavy, delayed period.

Faint positive hpt w/ first morn urine, neg dr. Urine test later that day, blood test came back post. Why was drs urine test neg? Early testing?

Pregnancy tests: Blood tests are more sensitive than urine tests, especially in early pregnancy. First morning urine is usually more concentrated than urine produced later in the day. Eating and drinking can dilute the urine enough to cause a false-negative result. That is why the blood test is done for confirmation. ...Read more
