Mgen positive, but resistance test negative?
I’ve tested positive for Mycoplasma genitalium twice and wanted to get a resistance test before starting antibiotics.
The lab used the same urine sample that had tested positive for Mgen. Now they’re saying the resistance test was negative because there wasn’t enough bacteria to reliably determine resistance, and they want me to submit another sample in two weeks.
I’m confused because it’s the same sample that was positive before. I understand that a low bacterial load can make resistance testing difficult, but this still seems weird to me.
Has anyone experienced this? Is this a normal limitation of Mgen resistance testing?
