The article also mentions that symptoms sometimes persist after treatment with antibiotics.
Could be a very big deal if it could be made properly inexpensive. COVID tests were, after all.
If you could know as soon as you were bitten whether there was any risk of infection at all, that would be very valuable information.
I think it's only a one in ten chance that an infected tick would transmit the infection, anyway. But you would know whether you needed to even book an appointment.
Only if the test is sufficiently accurate to rule out transmission. Even molecular tests can't reliably predict that.
So one more tool in the toolbox is a very good thing.
