What is this test?

This is a standardized questionnaire, rather than a laboratory test. It records the methods you use to prevent pregnancy and reduce the risk of sexually transmitted infections (STIs).

Why might I need this test?

A healthcare professional may use this information to review your reproductive health, discuss contraception and STI prevention, and determine whether additional counseling or protection is appropriate.

How is the test performed?

You or a healthcare professional complete a list of pregnancy-prevention and STD-protection methods, including whether you use hormonal contraception, condoms, or other approaches. No blood, urine, or other laboratory specimen is required.

How do I prepare for the test?

Review the contraception and protective methods you currently use or recently used. If helpful, have medication names, product names, or information about condoms and other barrier methods available for the visit.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.
