Blood test: a medical provider will take a small sample of your blood to test for infection.
- This test is commonly used for syphilis and HIV
A swab: a medical provider will take a sample from an infected area to test for a particular germ. This test is often performed on individuals who have symptoms but can be used on people without symptoms.
- This test is commonly used for Chlamydia and gonorrhea. Some rapid HIV tests also use swabs
Physical exam: a medical provider will perform a physical exam, looking at the infected area. This type of test is usually performed on individuals who are experiencing symptoms.
