The rates of false negative and false positive chlamydia tests for various types of tests are as follows (see related link):
Chlamydia is typically detected through urine or swab samples, not blood samples. Blood tests are not commonly used for diagnosing chlamydia.
A normal blood test will not detect the infection. To diagnose chlamydia, you need a urine test or swab of the vagina, urethra, rectum, throat, or eye. Blood tests can look for evidence of past infection with chlamydia, but these are of no use in determining current infection and aren't used to diagnose or treat disease.
Urine tests are accurate for the detection of anabolic steroids use. The urine samples are sent to laboratories for testing. Home steroid tests bought over the counter are also considered effective.
No, chlamydia cannot be tested through blood. It is typically diagnosed through urine or swab samples.
No, chlamydia cannot be detected through blood testing. It is typically diagnosed through urine or swab samples.
Urine tests are more accurate than hair tests.
Urine tests are effective for testing chlamydia, as long as the right test is ordered. A routine urinalysis or urine culture will not detect chlamydia. The specific chlamydia test needs to be ordered. There is a DNA amplification test that can be performed for chlamydia and gonorrhea on a urine sample. The urine, however, should not be a midstream sample - it should be the first urine that is urinated to get any of the bacteria that were growing in the urethra.
number of substances can interfere with dipstick tests. Examples of these are provided below. Please note that the effect of these substances will vary according to the type of test strip used. Commonly performed dipstick tests include:
Yes. A culture to detect bacteria in the urine does not check for chlamydia. The urine test for chlamydia is not a standard urinalysis or urine culture, but is a specific test to detect chlamydia's genetic material. Ask for the test specifically if you are concerned.
I believe they are fairly accurate, but probably not 99.9%. I've gotten false positives on urine tests before, but they're usually pretty accurate.
You may get positive leukocytes on a urine dip, but a person can have chlamydia and have no changes in urine other than those detected by a specific chlamydia test.
Pus cells from chlamydia may change the appearance of urine. Get tested if you think you're at risk of STDs.
