3 site testing for STI

  • 1.  3 site testing for STI

    Posted 30 days ago
    One more thing to blame on COVID.  Just what we all want to hear right?

    We are experiencing a shortage of the swabs used for 3 site testing (NAAT)  Our local labs have rationed them due to national supply shortage.

    We're continuing to do the 3 site testing, but with a twist, and I'm wondering if any other sites:
    1. have this supply issue
    2. have any literature or experience in alternate 3 site testing strategies
    3. other solutions.

    Here is what we've adapted to, using non NAAT testing swabs. 
    We do a urine (dirty catch).
    Have the patient swab there throat and put it in the urine cup (with urine)
    Have the patient swab their rectum and put in the urine cup (with urine)
    Mix the swabs in the urine, pipete the urine off and send.

    I know the treatment is the same regardless of site, so not concerned about that issue.  Just wondering if anyone has come across any literature on this?

    See CDC.gov/std.  They have recommendations on the website

    We don't have issues in PHX and use the APTIMA swabs. Consider using the same Swab and do a throat and rectal
    With the same stick then only send that one stick for both sites? The issue with urine is that it notoriously is less accurate than the swabs, and diluting the swabs into the urine might not catch smaller samples amounts of the bacteria.
