Yes — Here's How *Lab tests are a qualified medical expense. What that means for your FSA deadline, how to pay with the card, what the receipt needs to show, and how to spend a year-end balance well.* > Yes. Laboratory fees for diagnosing, monitoring or preventing a medical condition are a qualified medical expense under IRS Publication 502, so both HSAs and health FSAs cover them. At TestWell you pay with the HSA/FSA card at checkout, or pay normally and submit the itemized receipt — provider, date of service, each test and amount — for reimbursement. Physician authorization is included in the price. ## Recommended tests | Recommended | Type | Price | Why | | --- | --- | --- | --- | | [General Wellness Panel](https://www.test-well.com/tests/general-wellness-panel) | Panel (4 tests) | $89.99 | The annual baseline — CMP, CBC, lipids, TSH | | [Essential Health Panel](https://www.test-well.com/tests/essential-health-panel) | Panel (10 tests) | $189.99 | Adds A1c, vitamin D, iron and inflammation | | [Heart Health Panel](https://www.test-well.com/tests/heart-health-panel) | Panel (5 tests) | $99.99 | ApoB, Lp(a), hs-CRP with the lipid panel | | [Hemoglobin A1c](https://www.test-well.com/tests/hemoglobin-a1c) | Test | $21.99 | Three-month blood sugar average | | [Vitamin D, 25-Hydroxy](https://www.test-well.com/tests/vitamin-d) | Test | $41.99 | The most common deficiency to check before winter | | [Tuberculosis (TB) Blood Test](https://www.test-well.com/tests/tuberculosis-blood-test) | Test | $91.99 | School and employment requirements before January | All prices are cash-pay plus one $6 lab processing fee per order; physician authorization is included. ## Are lab tests FSA and HSA eligible? Yes. IRS Publication 502 lists **laboratory fees** among qualified medical expenses when they are part of medical care — diagnosing, treating, monitoring or preventing disease. Blood tests, urine tests and titers ordered through TestWell fall under that definition: every order is reviewed and authorized by a licensed physician, and the result is a CLIA-certified lab report. The same expense rules apply to both account types. The difference is the money: an **HSA** belongs to you, rolls over every year and can be invested; a **health FSA** is funded through your employer's plan year and, with narrow exceptions, forfeits what you don't spend. That difference is why lab testing spikes every December. One honest caveat: plan administrators decide what counts, and a small number treat "general wellness" screening differently from diagnostic testing. In practice, a physician-authorized lab order with an itemized receipt is accepted routinely; if your administrator asks for more, a short letter of medical necessity from your own clinician settles it. ## How do you pay with an FSA or HSA card at TestWell? Two ways, and neither needs a special form: 1. **Pay with the card at checkout.** HSA and FSA debit cards run as ordinary cards. TestWell is coded as a medical provider, so most cards approve automatically without a substantiation request. 2. **Pay another way and get reimbursed.** Download the itemized receipt from your account (or the link in your confirmation email) and upload it to your plan's portal. The receipt shows the provider, the date of service, each test by name, the amount paid and the payment method — the five fields substantiation asks for. The $6 lab processing fee is part of the same medical service and is itemized on the receipt. Prices are the same whether you pay with an HSA card, an FSA card or a regular card. ## When does FSA money expire? The use-it-or-lose-it calendar Health FSAs run on your employer's plan year — for most people, January 1 to December 31. Money not spent by the end of the plan year is forfeited unless the plan adopts one of two IRS-permitted exceptions (it can offer one or the other, or neither): - **Grace period:** up to 2 months and 15 days after the plan year ends (March 15 for a calendar-year plan) to incur expenses against the old balance. - **Carryover:** up to **$680** of unused 2026 funds roll into the next plan year (Rev. Proc. 2025-32; the 2025 carryover limit was $660). Anything above the carryover cap is forfeited. Your plan documents or HR portal say which applies to you. Two practical points for lab testing: the expense is "incurred" on the **date of the blood draw**, not the order date or the results date, so a December 30 order drawn on January 3 counts against the new year unless you have a grace period. And most plans require claims to be filed within a run-out window (often 90 days) after the plan year ends — keep the receipt. The 2026 health FSA contribution limit is $3,400 (Rev. Proc. 2025-32). HSAs have no deadline at all: 2026 contribution limits are $4,400 for self-only coverage and $8,750 for family coverage, plus $1,000 if you're 55 or older (Rev. Proc. 2025-19), and the balance is yours indefinitely. ## What should you spend a year-end FSA balance on? Spend it on the tests you'd want anyway — a leftover balance is a reason to stop postponing, not a reason to over-test. Sensible December patterns, by balance: - **Under $50:** one test you've been meaning to check — a [hemoglobin A1c](https://www.test-well.com/tests/hemoglobin-a1c) if you have a family history of diabetes, a [vitamin D](https://www.test-well.com/tests/vitamin-d) before winter, a [TSH](https://www.test-well.com/tests/tsh) if you've had thyroid symptoms, or a [ferritin](https://www.test-well.com/tests/ferritin) for unexplained fatigue. - **$90–$200:** the annual baseline. The [General Wellness Panel](https://www.test-well.com/tests/general-wellness-panel) covers the four tests a physical orders (CMP, CBC with differential, lipid panel, TSH); the [Essential Health Panel](https://www.test-well.com/tests/essential-health-panel) adds A1c, vitamin D, iron and inflammation markers. - **$200+:** the baseline plus the follow-ups your history suggests — the [Heart Health Panel](https://www.test-well.com/tests/heart-health-panel) (ApoB, Lp(a), hs-CRP) if heart disease runs in the family, hormone panels, or the [General Wellness Advanced Panel](https://www.test-well.com/tests/whole-body-essentials-panel) for a 14-test picture. - **Requirements with a January deadline:** a [TB blood test](https://www.test-well.com/tests/tuberculosis-blood-test) or [immunity titers](https://www.test-well.com/guides/titer-tests-proof-of-immunity) for school, clinical programs or a new job — cash-pay, HSA/FSA eligible, results in days. Order and draw before the plan year ends; results can post in January without affecting eligibility, because the expense date is the draw. ## What does the receipt include? Every TestWell order produces an itemized receipt in your account: TestWell as the provider (with the merchant of record that charged your card, so it matches your statement), the date of service, each test or panel by name, the $6 lab processing fee, the total paid and the last four digits of the card. That is the documentation plan administrators and the IRS expect for a qualified medical expense. Lab results themselves are never needed for substantiation — the receipt is enough. ## Frequently asked questions ### Can I use my FSA for blood tests without a doctor's prescription? Yes. FSA eligibility depends on the expense being medical care, not on how it was ordered. TestWell orders are reviewed and authorized by a licensed physician, which is what makes them lab tests rather than consumer products, and the itemized receipt documents the service. ### Does my HSA card work at TestWell checkout? Yes. HSA and FSA debit cards are accepted directly at checkout and run like any other card. If your card declines (some plans restrict online use), pay with a regular card and submit the itemized receipt to your plan for reimbursement. ### What date counts for my FSA — when I order, when I'm drawn, or when results post? The date of service — the day your blood is drawn. Order in December but draw in January and the expense belongs to the new plan year unless your plan has a grace period. Results posting later does not matter. ### How much can I put in an FSA or HSA in 2026? For plan years beginning in 2026 the health FSA employee contribution limit is $3,400, and plans that allow carryover may roll up to $680 into the next year (IRS Rev. Proc. 2025-32). HSA limits for 2026 are $4,400 for self-only and $8,750 for family high-deductible coverage, plus a $1,000 catch-up at age 55 or older (Rev. Proc. 2025-19). ### Are wellness panels eligible, or only tests my doctor ordered? Diagnostic lab tests are qualified medical expenses regardless of who ordered them. Some administrators ask for a letter of medical necessity for tests they classify as general wellness; if yours does, a note from your clinician stating the reason for testing is normally sufficient. Keep the itemized receipt either way. ### Can I pay for a family member's tests with my HSA? HSA funds can pay qualified medical expenses for your spouse and tax dependents even if they are not covered by your high-deductible plan. Health FSAs cover the employee, spouse and eligible dependents under the plan's terms. Each person orders under their own TestWell account, since results are private to the patient. ## Sources - [IRS Publication 502 — Medical and Dental Expenses (laboratory fees)](https://www.irs.gov/publications/p502) - [IRS Publication 969 — Health Savings Accounts and Other Tax-Favored Health Plans](https://www.irs.gov/publications/p969) - [IRS Rev.
