Frequently Asked Questions

Generally speaking, yes, you can use your HSA/FSA account to pay for an at-home health test. Your test is authorized by a physician, so it should fit the guidelines for most HSA/FSA coverage. If you have a particularly rigorous plan, it is best to check with your own plan if you’d like to verify before purchase.

Fasting helps ensure the most accurate results for certain blood tests—especially those measuring glucose, triglycerides, and cholesterol. Eating before your test can temporarily raise these levels, leading to misleading results.

If fasting is required, we’ll let you know in advance, usually asking you to avoid food and drink (except water) for 8–12 hours before your test.
