How can syphilis be diagnosed in a laboratory setting?2 marksa) Pap smear b) Blood test c) Urine test d) Visual inspection of genital sores

Syphilis can be diagnosed in a laboratory setting primarily through a blood test. This test looks for antibodies that are produced by the body in response to the infection. The antibodies can be present in the body for years, so this test can be used to diagnose current or past infections.

Visual inspection of genital sores can also be used to suggest the presence of syphilis, especially in the early stages of the disease when sores are present. However, this is not a definitive test as other conditions can cause similar sores. A sample from the sore would need to be examined under a microscope to confirm the diagnosis.

Pap smears and urine tests are not typically used to diagnose syphilis.
