If your health provider suggests you get a Pulsox test to measure blood oxygen levels at home while you sleep, do not use Lincare. Lincare uses a lab called VirtuOx to provide the test, and the lab has over a dozen outstanding complaints on the Better Business Bureau website. All billing is automated, they can't bill Oregon Health Plan, and they will not investigate billing errors. Instead, they'll just send you to a debt collection agency. Lincare continues to use VirtuOx, despite its reputation.
