Vitamin B12: common questions
How much does a Vitamin B12 test cost without insurance?
- The lowest self-pay price we track for Vitamin B12 is $9.79 at Mito Health, across 18 ordering services; the highest is $78.00. You pay the ordering service directly, and no insurance is involved. Prices were last verified on September 28, 2026.
Do you need a doctor's order for a Vitamin B12 test?
- No. Every ordering service listed on this page includes the physician order with the purchase, so you can buy Vitamin B12 yourself and take the requisition to the lab. Your results come back to you — what they mean is a conversation for you and a clinician.
Where is the blood drawn for a Vitamin B12 test?
- At a Quest Diagnostics or LabCorp patient service center, depending on which laboratory the ordering service you pick uses. You choose the location and time after you order. LabTestCompare does not draw blood, run tests, or issue results — we only compare what each service charges.
Can you use health insurance for a Vitamin B12 test?
- No. Every price on this page is a self-pay price paid directly to the ordering service, and none of these services bill insurance. If you want Vitamin B12 billed through your plan instead, that goes through your own provider — which is a separate route with its own cost, and worth comparing against the prices here.
Is this the same Vitamin B12 test a doctor would order?
- Yes — it is the same assay, identified by the same laboratory order codes: Quest #927 and LabCorp #001503. Every price on this page is matched to that code, which is how we can say the services are being compared on an identical test rather than on similarly named products.
How long do Vitamin B12 results take?
- That is set by the laboratory rather than by us. Routine blood tests are commonly back within a few business days and specialized assays take longer; the ordering service states the expected turnaround for Vitamin B12 before you buy, and delivers the result to you directly.
