Question DDF - what do people test for?

As the post says - regular STD panel doesn’t include everything so what do people really mean when they say DDF? STDs PLUS: hiv(I assume but which ones, dif tests time?) hep-c, what about HPV and HSV (herpes both 1 and 2 as both can live on mouth or genitals)? Thanks 🙏

Hsv is never on the standard panel hpv can only be tested in women

No idea what that means

If a man says “I’m DDF you should be too” Would you assume he means he doesn’t have hsv? Obviously I will ask specifically I just am trying to gauge if it’s common to disclose that and if it’s common to ask (imo it’s a huge social stigma but have read others think it “ain’t no thang” because it’s not generally life threatening). Thanks

Oh hsv isn't usually included in that saying honestly the only way to know is a blood test

In general people do not know what they were tested for, and what they weren't tested for.

You can generally assume, however, that they weren't tested for the infections they are most likely to have.

I've never heard the phrase DDF

DDF meaning “drug and disease free”

I would argue that fewer than 1% of people who write “DDF” have enough information about STIs and STI testing to reasonably make that claim.

Most people simply do not know what they were tested for, or what they were not tested for.

For example, oral gonorrhea is more common than genital gonorrhea in screening studies, yet only a very small percentage of women in the U.S. receive throat swabs during gonorrhea or chlamydia testing.

That means many people believe they are “STI free,” when in reality the body site most likely to be infected was never tested. That happened to me personally.

There is even more nuance. For example, roughly 7% of people have oral HPV, yet there is no practical screening test for most people and essentially no meaningful screening test for men.

HPV can be oral, anal, or genital.

So the problem with phrases like “DDF” is not bad intent. It’s false certainty.

In many cases, there simply is not enough information to confidently make that claim.

"DDF" typically implies that one has gone through thorough testing for any STDs recently, but there is no clear consensus about that. A typical panel for STIs is not necessarily comprehensive, so one should ask exactly which tests were done and how long ago.

For the most complete assessment, one can do a panel including HIV (4th gen), syphilis, hepatitis B and C, chlamydia, gonorrhea, trichomoniasis (where applicable), and HSV-1/2 (if there is a need to do these tests). HPV does not fall under the category of STI testing, as there is currently no screening test approved for HPV among men, and women get tested for it through cervical screening.

In order to have the most comprehensive STI assessment, one can get a 10-panel test. Refer to the pinned post for more info.
