Testing For Vitamin Deficiency

Doctors are able to diagnose vitamin deficiency through blood tests. These tests allow doctors to check the number and health of your red blood cells. Getting tested for vitamin deficiency consists of 4 easy steps:

  1. Schedule a blood test
  2. A trained professional will collect a blood sample from your arm
  3. The blood test is sent to a lab for processing
  4. Review your results

Doctors are able to identify advanced deficiency by reviewing your white blood cell and platelets count results from the blood test. They will also be able to see the amount of folate, vitamin C, and vitamin B-12 in your blood, as these deficiencies will trigger similar symptoms. 

If your doctor identifies a vitamin deficiency, they may perform additional blood tests to determine the exact type of deficiency. Such tests include an antibodies test or a methylmalonic acid test.

At-Home Tests For Vitamin Deficiency

An easier option is to purchase at-home vitamin deficiency tests. Some popular at-home tests include Everlywell, LetsGetChecked Micronutrient Test, and LetsGetChecked Essential Vitamin Test.


For $99 you can obtain the Everlywell Vitamin D and Inflammation Test, which measures both the 25-OH D and high-sensitivity C-reactive protein (hsCRP) levels in your body. The results will indicate how much vitamin D is in your blood and the amount of inflammation in your body.

The test will include everything necessary for a finger-prick blood sample, and it comes with a prepaid shipping so that you can return your sample. After the sample arrives back at the lab, physicians will review the results. On average, it will take five days to obtain the final results from your at-home test. The final results will come with a report so you can make diet adjustments, and you will also have an option to listen to a webinar led by a medical provider.

LetsGetChecked Micronutrient Test

This test costs about $200 and also includes a finger-prick test for at-home testing. After you receive your test kit, you have to register it online and follow the instructions listed in order to properly collect and return the sample for testing. 

Once the lab receives and processes the test, results will typically be returned in a few days. This test can check for various deficiencies in vitamins and minerals, including copper, vitamin D, zinc, vitamin E, vitamin B-12, magnesium, and selenium.
