Sexually Transmitted Infection Screening Tests

Sexually transmitted infection (STI) screening tests are medical procedures used to detect the presence of STIs, such as chlamydia, gonorrhea, syphilis, HIV, and others. These tests are typically performed on individuals who are sexually active or have been exposed to an STI.

Types of STI Screening Tests

• Urine Tests: Used to detect chlamydia and gonorrhea, these tests involve collecting a urine sample from the patient.
• Blood Tests: Used to detect HIV, syphilis, and other STIs, these tests involve collecting a blood sample from the patient.
• Swab Tests: Used to detect chlamydia, gonorrhea, and other STIs, these tests involve collecting a swab sample from the patient's genital area or throat.
• Pap Smear: A screening test for cervical cancer and human papillomavirus (HPV), which can be caused by certain types of HPV.

STIs That Can Be Detected Through Screening Tests

• Chlamydia
• Gonorrhea
• Syphilis
• HIV (Human Immunodeficiency Virus)
