Preparing for your STI Profile: MSM1 (Venous)
- 1Two weeks after exposure is the minimum for the urine and swab components; the blood tests for HIV and syphilis are most reliable from four to six weeks, with a repeat at twelve weeks to be certain.
- 2Hold urine for at least an hour before the appointment.
- 3Avoid douching or vaginal products for 48 hours before swabs.
- 4Think about which sites you have had sex with — oral, vaginal, anal — so the nurse can make sure the right swabs are included.
Sample for this test: swab, first-catch urine sample and venous blood sample (serum).
What STI Profile: MSM1 (Venous) measures
Laboratories file the STI Profile: MSM1 (Venous) under sexually Transmitted Infections, men who have sex with men and blood Test. The following sections set out how a STI screening profiles test of this kind is measured and read.
STI profiles combine several infections into a single visit. Entry-level screens test urine or a swab for chlamydia and gonorrhoea; mid-range profiles add blood tests for HIV, syphilis and hepatitis B; and the fullest screens include hepatitis C, herpes antibodies, Mycoplasma genitalium, trichomonas and ureaplasma. Profiles designed for men who have sex with men add throat and rectal swabs, and triple-swab female profiles sample the vagina, throat and rectum. Serology-only profiles cover blood-borne infections without genital sampling.
Who considers STI Profile: MSM1 (Venous)
- People often consider a full screen at the start of a new relationship, or before stopping condoms with a regular partner.
- After condomless sex with a new or casual partner, a comprehensive check is a common choice.
- Those with several partners often test at regular intervals, typically every three to six months.
- Symptoms that could have more than one cause make a profile more efficient than picking individual tests.
- Some people prefer a complete screen for reassurance even without a specific exposure.
Understanding your STI Profile: MSM1 (Venous) results
Each infection in the profile is reported separately, so a single positive does not affect the meaning of the others. Negative results are reassuring for the sites tested and the time since exposure, with the caveat that blood-borne infections tested early may need repeating at twelve weeks. Any positive result comes with a written explanation of treatment options, partner notification and whether a test of cure is recommended.
A profile is only as complete as the sites sampled and the timing since exposure, and no combination of tests covers every possible infection.
If you may have been exposed to HIV within the last 72 hours, or have severe symptoms such as high fever with pelvic pain, contact an emergency department or sexual health service now — do not wait for a scheduled screen.
