False positive! I will be double checking this with the local lyme expert on Friday, but it was his *IGm* not IGg that was positive, which would indicate an infection in the last month or so. Since he couldn’t have gotten sick in the last month, it’s probably a false positive. Not only that, every single lab other than the IGm was normal, so he doesn’t seem to be sick at least according to his bloodwork. He doesn’t even have any allergies.
This still leaves open questions, like whether he’s got something else that’s making him tired and sick a lot. On the other hand, he’s 4 and in school, and likely to pick lots of things up. I wish it were easier to know when to worry and when not to.
**** UPDATE **** we have since confirmed that this was a *POSITIVE* test, despite what is said above. See “Diagnosing Lyme in my son” for more details.
