Will this be reimbursable through insurance as other blood draws are?

Unlikely (unfortunately).

I work at a startup which offers blood testing—it costs $190 when consumers pay in cash, and when we've tried going through insurance, it ends up about $1400-$1500.

The "insurance-negotiated" rate is massively inflated, and some of the more advanced biomarkers (e.g., ApoB) generally don't have insurance coverage.
