Many people think that a yellow or green nasal discharge means a bacterial infection, which requires antibiotics but it is not true. It can be a sign that your body is being attacked by either a bacteria or a virus. That said, a yellow discharge does not necessarily indicate a sinus infection.
After the stool is placed in the culture, it may take two to three days for any bacteria that is in the stool to grow. These bacteria can then be isolated and examined under a microscope so that they may be identified. The stool may also be tested for parasites or eggs.
In summary, these are usually available within two days of the test taken. Hepatitis tests generally take three days to arrive, and herpes cultures come back about four days after the test. HIV results are available to the patient within 25 minutes of taking the test. Usually about 1-2 weeks. Some times no news is good news but you may want to phone you're doctor and ask if or when they will have your results for you. Depending on the test, you should have results within 1 to 2 days.
