Another fail for the health care reimbursement model in the US. Understand that I am very supportive of what you feel, and I'm just trying to explain what I think is going on.
The urgent care staff, is URGENT care; they give a lot of verbal info and instruction, many times it'll be wrong and harmless, or wrong and really annoying; but rarely wrong and dangerous. This instance is wrong and annoying. If the lab is going to grow a culture, 2-3 days is a very unlikely time frame for results. So I just have to assume the error is with the verbal instruction.
I don't want to comment on the Kaiser part; as I seem to make people really upset when I talk about our lovely American system... I doubt they are being discriminatory, but they may have no solid protocol in place to accommodate the added complexity of transgender conditions, thus producing a medical version of Keystone Kops.
