Preparation checklist for the Vitamin & Nutritional Testing
No routine preparation is generally necessary for vitamin and nutritional testing. However, the testing location can advise on any specific timing or fasting requirements for your test.
- Confirm with the lab whether fasting is required for your specific test panel.
- If fasting is needed, avoid all food and drinks except water for the recommended time before collection.
- Stay hydrated by drinking water unless told otherwise.
- Avoid taking vitamin supplements on the morning of the test unless your healthcare provider instructs otherwise.
- Inform the lab staff of any medications or supplements you are taking.
- Wear a short-sleeved shirt to allow easy access to your arm for the blood draw.
Fasting, timing, sample type, and what to bring
Fasting
Fasting may or may not be required depending on the specific tests included in your panel. Some vitamin tests, like vitamin D, do not require fasting, while others may be affected by recent food intake. Always confirm with your lab.
Best time to collect
The best time to collect the sample is typically in the morning, especially if fasting is required. This allows for consistent results and ensures you have not eaten for the recommended period. Your lab can provide specific timing instructions.
Sample type
Blood draw. The collector will explain the process before starting.
What to bring
- Your order confirmation email, in case the collection site asks to see it
- Your printed lab order or requisition form — the ordering physician prepares it for you after you order, and you print it (or fax it from your account) before visiting
- A short-sleeved or loose-sleeved shirt for an easy blood draw
- Water to drink before the draw and a light snack for afterward, if your test requires fasting
- A government-issued photo ID (most collection sites verify identity at check-in)
- A written list of the medications and supplements you currently take
You do not need an insurance card or a payment method at the collection site: the lab does not bill insurance, and you pay at order time, so there is no copay or deductible. The lab also provides the physician's requisition, so you do not need a separate doctor's referral.
Order process and what-to-bring details reflect the lab's published instructions, paraphrased in our own words. Confirm final requirements with the collection lab that will perform your draw.
What the collection involves
A healthcare professional will draw a small amount of blood from a vein in your arm using a needle. The sample is then sent to a laboratory for analysis, and results are typically available within a few business days.
Details worth confirming with the collection lab before your visit:
- Do I need to fast before this test?
- Should I avoid taking my vitamin supplements before the test?
- When will my results be available?
When this test is useful

What results mean
