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.

Fatigue, brain fog, numbness or tingling, weakness, or balance problems with a borderline B12 result Confirming whether a low-normal serum B12 reflects true deficiency Following a vegan or vegetarian diet, or taking metformin or acid-reducing medication long term Separating B12 deficiency from folate deficiency before starting treatment Monitoring response after starting B12 supplementation or injections. Limitation: No additional limitation was recorded in the authority row.

Measures: Substance concentration Methylmalonic Acid Methylmalonic acid builds up in your blood when cells lack the B12 they need to run a key metabolic reaction, making it a sharper, more specific marker of B12 status than serum B12 itself.

Order online, choose an available laboratory for your state and confirm the complete price before paying. Membership is optional.

Collect

Confirmed

Fasting is generally recommended because recent meals and B-vitamin intake can change homocysteine. Report B12, folate or B6 supplements and any B12 injections, including dose and timing, because supplementation lowers these metabolites and can mask deficiency. Kidney impairment can raise both markers independently of B12 status. Attend a participating laboratory for blood collection.

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

  • Includes Homocysteine, Methylmalonic Acid.
  • Order online for blood collection at a participating laboratory.
  • Clinician-reviewed results are available without membership.

Watch-outs

  • Quest Diagnostics: $39.92 without membership or $28.51 for members in other states and Washington, DC.
  • Not currently available in New Jersey, New York and Rhode Island.
  • Fasting is generally recommended because recent meals and B-vitamin intake can change homocysteine. Report B12, folate or B6 supplements and any B12 injections, including dose and timing, because supplementation lowers these metabolites and can mask deficiency. Kidney impairment can raise both markers independently of B12 status.
  • A specific turnaround has not been confirmed. Results are delivered to your dashboard with clinician review. Actual timing depends on laboratory processing.
  • Membership is optional. It costs $9 per month and can be canceled anytime; member prices apply with membership, and nonmembers can order at listed nonmember prices.
  • Optional live consultations cost $39 for members or $99 for nonmembers and are separate from the test fee.
  • Applicable order or draw fees are itemized before payment. The complete fee amount for the selected laboratory route is not established.
  • Complete analytical performance, actual report ranges and uncertainty, and laboratory-specific specimen retention have not been confirmed.
  • Methylmalonic Acid is more specific to B12 status, while Homocysteine can rise with B12, folate or B6 shortfall; the pair still needs clinical interpretation.
  • Fasting, B-vitamin supplements, B12 injections and kidney impairment can affect these markers independently of the question being investigated.
  • This panel helps investigate functional deficiency but does not by itself diagnose the cause of symptoms or determine treatment.
