A single targeted test — ferritin, vitamin D or B12 — is usually the cheapest way to answer a specific question. Broad micronutrient panels cost several times more and measure many markers that don’t yet have agreed thresholds for action. For most people, a narrow, targeted test is usually the right place to start.

Is it worth it?
Ferritin only
Iron stores
$59
Only in panels
Often the single most useful first test for tiredness.
Iron panel with ferritin
Serum iron, TIBC, saturation, ferritin
$189 (Anemia Test, also adds CBC, B12 and folate)
$59
The full picture for iron; lets you read the pattern.
25-OH vitamin D
Vitamin D status
$99
$75
Worth it if you have limited sun exposure or risk factors.
Vitamin B12
B12
$49
$49
Useful with a plant-based diet, metformin or acid-reducing medicines.
Vitamin B12 + folate
B12 and folate
$89
$82
Adds folate, the other vitamin needed to make red blood cells.
6-nutrient panel
Vitamin D, B12, folate, magnesium, iodine, zinc
$239
$239
Leaves out ferritin and iron, even though iron is among the most common deficiencies.
10-nutrient panel
The six above plus vitamins A, C and E and ferritin
$485
$215–$299 (8–11 nutrients, by condition)
Most expensive; many markers lack clear treatment thresholds.
Prices exclude temporary sales, which both sites run often. Quest adds a physician service fee (from $6) to each order. Both labs’ 6-nutrient panels test the same six markers. Quest’s larger nutrient panels are built around a condition (for example celiac disease, IBD or pregnancy), so their markers differ from Labcorp’s.
Four things that change the price
Who orders it. A test ordered by your doctor because of symptoms is often covered by insurance. Direct-to-consumer tests usually aren’t, though many are HSA/FSA eligible.
How the sample is taken. A blood draw at a patient service center and an at-home finger-prick kit can cost very different amounts for the same marker — and finger-prick samples can’t run every test.
Serum vs. intracellular. Standard tests measure levels in blood serum. Some specialty panels measure nutrients inside white blood cells. These are sold by specialty labs rather than Labcorp or Quest, and are not part of routine clinical guidelines.
Panel size. Price climbs with marker count, but usefulness doesn’t. A 10-marker panel doesn’t tell you ten times as much.
How to spend less and learn more
Start from the question: tiredness, hair loss, a restrictive diet, a medication known to deplete a nutrient.
Pick the one or two markers that answer it. For tiredness in someone who menstruates, that is usually ferritin.
Ask your clinician first — if there is a clinical reason, insurance may cover it.
Only then consider a broader panel, and ask what you would do differently with each extra result.
When a broader workup makes sense
Starting narrow is the usual advice, not a rule. Some people need a wider set of tests, chosen by a clinician rather than bought as a direct-to-consumer panel:
Conditions that affect absorption, such as celiac disease or inflammatory bowel disease (IBD)
After bariatric (weight-loss) surgery
Chronic kidney disease
Pregnancy
An eating disorder, alcohol use disorder, or a very restrictive diet
Neurologic symptoms such as numbness, tingling, balance problems or memory changes
If any of these apply, talk to your clinician before choosing a test yourself.
Common questions
Does insurance cover micronutrient testing?
Often, when a clinician orders a specific test for symptoms or a known risk. Broad wellness panels and direct-to-consumer tests are usually not covered, though many can be paid with HSA or FSA funds.
How much does a ferritin test cost without insurance?
Labcorp OnDemand lists a ferritin test at $59. Quest sells ferritin only as part of panels; its iron, TIBC and ferritin panel is $59 plus a $6 physician fee (list prices, checked Sep 20, 2026).
Is a comprehensive micronutrient panel worth it?
For most people, usually not. Targeted tests for the nutrients most often low — iron, vitamin D and B12 — answer the practical questions for far less money, and broad panels include many markers without agreed treatment thresholds. People with absorption problems, bariatric surgery, kidney disease, pregnancy or neurologic symptoms may need a broader workup, which their clinician should direct.
What is the cheapest useful micronutrient test?
Usually a single ferritin test. Iron deficiency is among the most common nutrient deficiencies worldwide and the leading nutritional cause of anemia, and ferritin is the best single marker of iron stores.
