Blood Testing Services in London Ontario
You can access a wide range of blood tests at local labs, hospitals, and clinic-based collection sites. Booking options, preparation requirements, and result delivery vary by provider and test type.
Types of Blood Tests Available
Labs in London offer routine and specialized tests. Common routine panels include Complete Blood Count (CBC), Basic Metabolic Panel (BMP), lipid profile, liver enzymes, and thyroid-stimulating hormone (TSH). These cover screening for anemia, electrolytes, cholesterol, liver function, and thyroid disorders.
Specialized testing includes HbA1c for diabetes control, vitamin D and B12 levels, infectious disease serology (e.g., hepatitis, HIV), coagulation studies (INR, PT/PTT), and hormone panels. Some centres provide genetic testing, autoimmune markers (ANA, rheumatoid factor), and allergy-related IgE testing.
Check whether the test requires fasting, morning collection, or medication adjustments. Community labs such as Dynacare, LifeLabs, and AlphaLabs typically list specific instructions online. Hospitals and specialty clinics may handle complex or inpatient-only tests.
How to Book an Appointment
You can book online, by phone, or by walking in, depending on the provider. Dynacare and LifeLabs offer online check-in and appointment slots; AlphaLabs and local hospital labs may support e-ordering through your clinician.
Bring a valid photo ID, your health card (if applicable), and any lab requisition forms from your physician. If you use private-pay services, confirm pricing and whether prepayment is needed. For faster service, choose an appointment time outside peak morning hours and complete online check-in where available.
If you need accommodations—wheelchair access, quiet rooms, or sensory-friendly collection—call ahead to request them. For urgent or same-day tests ordered by your clinician, call the lab to confirm priority processing.
Understanding Test Results
Your provider or the lab portal will return results as numeric values and reference ranges. Focus first on whether values fall inside or outside the stated reference range; labs often flag abnormal values.
Interpretation depends on context: a mildly elevated liver enzyme may require repeat testing, while a markedly abnormal glucose or low hemoglobin usually prompts immediate clinical follow-up. Compare current results with prior tests when available to assess trends.
If results are unclear, contact the ordering clinician to discuss implications, next steps, and whether further diagnostics or treatment adjustments are needed. Use secure patient portals (e.g., MyCareCompass or lab-specific portals) to access electronic reports and downloadable PDFs for your medical records.

Choosing Blood Test Providers in London Ontario
You should evaluate labs for accreditation, convenience, and cost before booking. Focus on whether the lab accepts your requisition, is near your home or workplace, and whether your insurer or OHIP covers the test.
Accredited Laboratories
Choose a lab accredited by recognized bodies such as the Ontario Laboratory Accreditation program or CPA (College of American Pathologists) equivalents used by major providers. Accreditation confirms quality control, staff qualifications, and validated testing methods.
Ask the lab which specific accreditation(s) they hold and whether the test you need falls under that scope. Some small collection sites forward samples to larger accredited central labs; confirm where analysis occurs and how results are reported to your clinician.
Check for published test directories or online test info pages that list methods and turnaround times. If you need specialized tests (hormone panels, genetic tests, or uncommon serologies), verify the lab’s experience with those assays to avoid delays or repeat draws.
Location and Accessibility
Pick a site with hours and access that match your schedule. LifeLabs, Dynacare, Alpha Labs and hospital collection sites in London offer a mix of walk-in and appointment options; confirm online check-in or bookable slots to minimize wait times.
Consider parking, public transit links, and accessibility features if mobility is a concern. Some community collection centres operate inside clinics or pharmacies—these may close earlier than hospital-affiliated sites, so check closing times before you travel.
If you require fasting, timed draws (e.g., post-glucose testing), or multiple draws on the same day, choose a facility experienced with those protocols. Also ask whether the site sends electronic results to your provider or offers patient portals for direct access.
Costs and Insurance Coverage
Confirm whether OHIP covers your specific test; routine blood work ordered by an Ontario clinician is often covered, but private or specialized tests may not be. If OHIP does not apply, ask for a written cost estimate before the draw.
Check whether your private insurance reimburses out-of-pocket fees and whether the lab will submit claims on your behalf. Some labs display standard fees online; for non-standard panels, request itemized pricing for transparency.
If you face urgent timelines, ask about expedited processing fees. Also verify billing practices: whether you pay at collection or are invoiced later, and what payment methods are accepted.
