Which Blood Tests Are NOT Covered by OHIP in Ontario?

While OHIP covers most medically necessary lab work, several commonly requested tests fall outside standard coverage, or are only covered under specific conditions.

Tests OHIP does NOT routinely cover

• Vitamin D (25-hydroxy vitamin D) — One of the most frequently requested tests, but OHIP only covers it if you have an established condition such as osteoporosis, osteopenia, celiac disease, or another malabsorption disorder. For all other patients, you'll pay out of pocket (typically $40–$60).

• Prostate-Specific Antigen (PSA) — Only covered by OHIP if you have a confirmed prostate cancer diagnosis and are in active treatment or follow-up. Routine screening PSA tests are not covered.

• Aspartate Aminotransferase (AST) — Only covered when ordered by a physician who specializes in liver diseases. General practitioners ordering this test will result in a patient-pay charge.

• Testosterone (routine wellness) — Not covered for general wellness or optimization purposes; requires a documented clinical indication.

• Celiac disease screening (tTG IgA / serum IgA) — Currently covered under a provincial pilot program for undiagnosed patients over age 2 who are consuming a gluten-containing diet. Coverage has been extended through the pilot; confirm with your lab before visiting.

• Specialized hormone panels, genetic testing, and executive wellness panels — These are considered elective or non-standard and are generally not covered.

Important: Your healthcare provider is required by OHIP rules to write "uninsured" beside any test on your requisition form that is not covered. The lab will inform you of any out-of-pocket costs before collecting your sample, so you can choose to decline.

If you regularly need tests that fall outside OHIP's coverage, a private individual health insurance plan may help offset those costs. Many extended health plans include a health spending account or diagnostic coverage that applies to uninsured lab work.

How Much Does a Blood Test Cost in Ontario?

The price of blood tests in Ontario can vary significantly based on several factors, including the type of test being performed, the facility where the test is carried out, and whether you have insurance coverage. The cost of a standard blood test ranges from $30 to $300 on average, but ultimately depends on its complexity and the laboratory processing it.

More common blood tests, like complete blood count (CBC), metabolic panels, or lipid profiles, fall on the lower end of this spectrum. On the other end of the spectrum are specialized tests, such as hormone panels or genetic testing. These can be much more expensive, as they’re less common and usually require more complex processing. 

For those without insurance, discussing costs upfront with the healthcare provider or laboratory can help manage expectations and allow for informed decisions regarding care. If blood tests are performed in conjunction with other medical evaluations, which they usually are, costs will escalate if not properly accounted for. 

Blood Tests Covered by OHIP

The Ontario Health Insurance Plan (OHIP) does cover certain blood tests, but not all of them. To qualify for OHIP coverage, blood tests must be deemed medically necessary and ordered by a licensed healthcare provider. Here are some key points about OHIP coverage for blood tests:

Medically Necessary Tests

OHIP provides coverage for blood tests that are required for diagnosing or monitoring specific medical conditions. This typically includes tests ordered by doctors during a clinical examination where the results are essential for treatment planning. Some of the commonly covered tests include:

1. Complete Blood Count (CBC): This test assesses overall health and detects a range of disorders, including anemia, infection, and several other diseases.

2. Metabolic Panel: This test evaluates blood glucose, electrolytes, and kidney function which provide insight into your body’s chemical balance and metabolism.

3. Lipid Profile: Often performed to assess risk factors for heart disease, this test measures cholesterol levels and other fats in the blood.

4. Thyroid Function Tests: These tests check the thyroid gland’s performance and diagnose thyroid disorders.

Cost of Blood Tests Without OHIP

Here’s what you can expect to pay out of pocket without OHIP. All the blood tests listed below would usually be covered by OHIP.

Please note that these are just approximate cost ranges. Cost can change at any time and varies based on healthcare provider.

1. Testosterone: $20–$30

2. Hepatitis B: $15–$20

3. Hepatitis C: $15–$20

14. Vitamin B9 (Folate): $30–$40

15. Blood Clotting Test (PT/INR): $10–$15

16. Ferritin: $15–$25

17. Serum Potassium: $5–$10

Referrals and Orders

To ensure that blood tests are covered by OHIP, they must be ordered by a physician or healthcare professional who is registered with OHIP. This will call for a visit to your family doctor or a specialist who can recommend the appropriate tests based on your medical history and current symptoms. Whoever you’re consulting with should evaluate the urgency and necessity of these tests.

Laboratory Locations

Blood tests performed in public hospitals and community health clinics are generally covered by OHIP, provided they are deemed medically necessary. However, tests done at private laboratories may incur out-of-pocket costs unless the tests fall under specific OHIP coverage. Before proceeding with any tests, it’s advisable to confirm with your healthcare provider whether the lab accepts OHIP and that the tests ordered will be covered.

FAQ: Can I get a blood test without a referral?

Yes, you can get a blood test without a doctor’s referral — however, it most likely won’t be covered by OHIP.

To get a blood test without a referral, you can make a request online or in-person at a private clinic. The clinic will then provide you with a blood work requisition. You must pay out-of-pocket or with private insurance.

How to Get a Blood Test Without a Family Doctor in Ontario

Not having a family doctor is increasingly common in Ontario. If you're without a primary care provider, you still have several ways to get blood work done — both through the public system and privately.

Option 1: Walk-In Clinic

Walk-in clinics in Ontario can order blood work on your behalf. If the tests are medically necessary and the clinic physician is registered with OHIP, the requisition is OHIP-covered and you can take it to any community lab such as LifeLabs or Dynacare. Wait times at walk-in clinics vary, and not all clinics routinely order comprehensive panels.

Option 2: Virtual Care / Telehealth Platforms

Licensed physicians and nurse practitioners operating through virtual care platforms can issue blood work requisitions in Ontario via secure online messaging — no video call required in many cases. Most OHIP-eligible tests ordered this way are covered by your health card; a consultation fee may apply for the virtual visit itself, which may or may not be covered depending on the service and the nature of your concern.

Option 3: Private Lab Ordering Services

Several Ontario-based services allow you to order blood tests directly online. You select the panel, a licensed clinician reviews your intake and issues a requisition, and you bring it to a partner lab (LifeLabs, Dynacare, or AlphaLabs). OHIP-eligible tests on the requisition are still covered by your health card — you generally only pay for the consultation and for any elective or non-OHIP tests you request.

Option 4: Naturopathic Doctors (ND)

NDs in Ontario can order blood tests, but tests ordered by a naturopath are not covered by OHIP — this includes tests that would otherwise be OHIP-insured if ordered by a physician. You will pay out of pocket. However, some private extended health plans include coverage for naturopathic lab work, so it's worth checking your benefits.

What to Bring to the Lab Regardless of how you obtain your requisition, always bring:

• Your Ontario health card (green card)

• A valid photo ID

• Your signed requisition form (paper or electronic, depending on the lab)

Note that your requisition form is typically valid for six months from the date it was issued. If you don't use it within that window, you'll need a new one.

If you don't have OHIP yet — or your coverage has lapsed — a guaranteed acceptance health insurance plan can bridge the gap while you establish full coverage.

When OHIP Coverage is Denied

If you find OHIP coverage was denied for your blood test, this would mean the test was considered for routine screening or preventive measures rather than a response to specific health issues. Additionally, tests that are performed without a physician’s order, or those not listed under the approved services, will typically not be covered.
