The Test Grade. The Reason Behind It.

Potentially useful for the right buyer, with meaningful evidence, coverage, transparency, access, cost, terms, or privacy tradeoffs to review.

A lower grade does not mean a panel is a bad personal fit. Your Fit Score can be higher when its purpose, price, sample, access, or support matches what you need.

Sample and fulfillment journey

Order

Confirmed

Choose this test, your state and an available laboratory online. Mito provides the laboratory order when required.

Panel-specific source · Source dated September 10, 2026

Collect

Confirmed

Visit the selected laboratory for a blood draw. Labcorp test 006452 requests 1 mL serum, which is preferred, or plasma for adults, accepts red-top, gel-barrier or heparin tubes, and requires removal from cells within 45 minutes with transfer to a plastic transport tube. Quest test 351 requests refrigerated transport in a transport tube and identifies an immunoturbidimetric C3c measurement. Exact BioReference technical handling for code 0532-2 was not independently assessed, so follow that laboratory's order-specific instructions. Fasting and specific timing are not required by Mito. Note active or recent inflammation or infection because C3 can rise as an acute-phase response and may affect interpretation. Follow the selected laboratory's complete order instructions.

Reading the labels

What Has Been Checked?

Source collected

Evidence labels stay separate from the Test Grade. They show how much source support exists for the evaluation.

The balance

The Strengths. The Tradeoffs.

Strengths

  • Online ordering includes the required laboratory order through Mito.
  • Measures complement component C3 concentration in serum or plasma as one result. Quest labels order 351 Complement Component C3c, while Labcorp labels order 006452 Complement C3. This is not C4, C3a desArg, C4a, CH50 functional activity, an autoimmune panel or a diagnosis.
  • Results are delivered to the Mito dashboard after laboratory processing.

Watch-outs

  • Labcorp and Quest are offered in 47 states and Washington, DC; BioReference is offered in NJ, NY and RI. Laboratory selection and price depend on your state.
  • The starting test price of $13.63 is the Labcorp nonmember option outside NJ, NY and RI, before its separate order fee. Other laboratory options have different prices and fees.
  • Labcorp test 006452, for 47 states and Washington, DC, excluding NJ, NY and RI: $13.63 without membership or $9.73 with optional $9 monthly membership, plus a separate $11.50 order fee.
  • BioReference test 0532-2, for NJ, NY and RI: $22.68 without membership or $16.20 with optional $9 monthly membership, plus a separate $9.50 order fee.
  • Quest Diagnostics test 351, for 47 states and Washington, DC, excluding NJ, NY and RI: $25.32 without membership or $18.08 with optional $9 monthly membership, plus a separate $15.00 order fee.
  • Membership is optional. The final checkout total, cancellation and refund terms remain unverified.
  • Typical results take 1-2 days; this is not a guaranteed order-to-result deadline.
  • Complement C3 concentration is not a diagnosis and does not measure complete complement-system function. Labcorp states that its assay detects biologically active and inactive C3, and Quest labels its target C3c. Interpret the laboratory-specific result with C4, CH50 when clinically selected, current inflammation, symptoms and clinician guidance.
  • Fasting and specific timing are not required by Mito. Note active or recent inflammation or infection because C3 can rise as an acute-phase response and may affect interpretation. Follow the selected laboratory's complete order instructions.
  • Results appear in the Mito dashboard after laboratory processing. A personalized action plan requires membership; live consultations cost extra.
  • This test is marked HSA/FSA eligible. Your plan determines individual eligibility and reimbursement.
