Dear Annie: I lost my job in a restructuring in early 2008, and have spent most of the time since then training for a new career. I'm still covered by COBRA, so I have health insurance now, but that will expire in a couple of months, so I'll have to go get my own insurance.

Knowing one way or the other would help me plan better for things like how much retirement income I might need to cope with extra medical expenses, or how heavily to invest in long-term care insurance. Here's my question: If I get the test and it comes out positive, can insurers turn me down for medical insurance? -Just James
