The most common is called the rapid influenza antigen test, or rapid influenza diagnostic test. This type of test can provide results in less than half an hour, but is not as accurate as some other types of flu tests. More sensitive tests may require your health care provider to send samples to a specialized lab.

Tests that may be used to diagnose URIs are: Throat swab: Rapid antigen detection can be used to diagnose group A beta-hemolytic strep quickly. Lateral neck X-rays: This test may be ordered to rule out epiglottitis if you have difficulty breathing. Chest X-ray: Your doctor may order this test if they suspect pneumonia.

A rapid strep test involves swabbing the throat and running a test on the swab. The test quickly shows if group A strep is causing the illness. If the test is positive, doctors can prescribe antibiotics. If the test is negative, but a doctor still suspects strep throat, then the doctor can take a throat culture swab.

Oral fluid HIV tests are very accurate. In studies, the OraQuick In-Home HIV Test detected 91.7 percent of people who were infected with HIV, and 99.9 percent of people who were not infected with HIV. If you have more questions about oral fluid HIV tests, talk to your doctor or healthcare provider.

Blood tests for STDs and STIs are more accurate at diagnosing infection than are cell swabs or urine tests. A swab may miss the area of the infection and result in a false negative if the primary site of the infection is located in a different area than the swabbed region.

If the rapid strep test indicates a strep infection, the doctor usually will prescribe antibiotics. Keep in mind, though, that up to a third of negative rapid strep test results are false (meaning someone actually has a strep throat infection even though the rapid strep results were negative).

Data from the CDC suggest that for both STIs, a false positive is incredibly rare (99 percent of the time tests that come back negative are accurate). And if you do have the STI, it'll pick it up more than 90 percent of the time.

Test Accuracy If you read the instructions carefully, most tests promise 99% accuracy on the day of your missed period—but not for early results.

Very few medical tests have 100% accuracy. There will still be rare cases where someone is HIV positive and not picked up. However, HIV tests are one of the more accurate tests for any medical infection. Tests showing a negative result are 'interpreted' as negative.
