What STDs Show Up in a Blood Test?
Sexually transmitted diseases (STDs) are infections that are spread through sexual contact. They can have serious health consequences if left untreated. While some STDs can be diagnosed through physical examinations and tests like urine samples or swabs, others require a blood test to detect the presence of the infection. Here, we will discuss some common STDs that can be detected through blood tests.
1. HIV/AIDS: Human Immunodeficiency Virus (HIV) and Acquired Immunodeficiency Syndrome (AIDS) can be diagnosed through a blood test that detects antibodies or antigens present in the blood.
2. Syphilis: This bacterial infection can be detected through a blood test that detects antibodies against the Treponema pallidum bacteria.
3. Hepatitis B: A blood test can detect the presence of HBsAg, a protein on the surface of the hepatitis B virus, indicating an active infection.
4. Hepatitis C: Similar to hepatitis B, a blood test can detect the presence of antibodies against the hepatitis C virus.
5. Herpes: While herpes is commonly diagnosed through physical symptoms, a blood test can confirm the presence of the herpes simplex virus (HSV) antibodies.
6. Chlamydia: Chlamydia is usually diagnosed through a urine or swab test. However, a blood test can be used in some cases, although it is less common.

13. Pubic Lice (Crabs): Pubic lice are diagnosed through visual examination of the affected area. Blood tests are not necessary for diagnosis.
