Multiplex Immunoassay Panel for Vitamin and Nutrient Levels (Serum/Plasma)

This vitamin and nutrient panel typically measures key levels such as vitamin D, vitamin B12, folate, iron, ferritin, calcium, and magnesium, giving your healthcare provider a clear picture of your overall nutritional status and helping identify any deficiencies that may affect your health.

This panel typically includes tests for vitamins like vitamin D, B12, folate, and others, as well as minerals such as iron, zinc, and magnesium. Some tests may also measure antioxidants like selenium or vitamin C, depending on the specific assays included. The results help identify deficiencies or excesses that could affect your health.

Your doctor may recommend this test if you have symptoms such as ongoing fatigue, weakness, hair loss, brittle nails, or frequent infections, or if your diet, certain medications, or a digestive condition may be preventing your body from absorbing enough essential nutrients.

Your doctor may recommend this test if you have symptoms like fatigue, weakness, frequent infections, or unusual cravings for certain foods. It’s also used in screening for conditions like anemia, vitamin deficiencies, or metabolic disorders. Some patients may need it before starting certain treatments or medications.

In many cases, you will be asked to fast for 8 to 12 hours before your blood sample is collected, so a morning appointment is often the most convenient option. Drink plenty of water, tell the staff about all medications and supplements you take, and follow any specific preparation instructions from your provider.

You’ll likely have a simple blood draw, usually from a vein in your arm. Fast your blood for 8–12 hours before the test if instructed, but check with your lab for specific guidelines. Wear loose clothing to make the process easier, and bring any medications or supplements you’re taking to discuss with your provider.

After the blood draw, a small bandage will be placed over the puncture site, and you can usually return to your normal activities right away. If you fasted, having a snack and some water afterward can help you feel your best, and mild soreness or slight bruising at the site typically fades within a day or two.

The blood sample is sent to a lab for analysis using advanced immunoassay methods. Results are usually available within a few days, depending on your lab. You’ll receive a report with your individual results, which your doctor will review to determine if any adjustments to your diet, supplements, or treatment plan are needed.
