A short YouTube transcript excerpt of Robert Whitfield MD explaining what biofilm is, describing limitations of traditional culture methods (swab/agar plate incubation) that can yield false-negative results in implant infections, and recounting a clinical case that led them to adopt PCR-based testing which detects DNA fragments and is more sensitive.
This is a biofilm. And we'll explain what biofilm is shortly. So I sent them off. And traditional techniques for everybody listening, it's like taking a Q tip and wiping it around in the pocket or on the surface of the implant and sending it off. They put it in a. What's called an auger plate, rub it around and incubate it. That's been done, you know, forever. That's always been the standard. And it came back and said there was absolutely nothing on this implant. And I was like, oh, my gosh, that's completely. Now I'm really aggravated because I went out. I know there's a problem. I went out and told her spouse. I'm like, she's gonna be fine. As soon as I figure out what this is, we'll treat it and be fine. Because of that experience, we switched to what's called that. Everybody knows this from the pandemic, a PCR test. So in the pandemic, you take an antigen test or you take PCR test. PCR tests. It's based on DNA fragments, so it'll tell you exactly what's there.
