Vitamin B2 (Riboflavin) Blood Test

The B vitamins are all crucial for cell metabolism, normal functioning of the central nervous system and the formation of red blood cells. This test measures the level of vitamin B2 in your blood.
Blood sample 1 test included 8 working days turnaround


Altogether, there are 8 B vitamins, each with their own purpose and role within the body. The B vitamins are all water-soluble and crucial for cell metabolism, normal functioning of the central nervous system and the formation of red blood cells. All the B vitamins we need should be available through our diet. The B vitamins help with the conversion of food into fuel and metabolising fats and proteins. 

Vitamin B2 is found in foods like almonds, whole-grains, mushrooms, certain dairy products, eggs, brewer’s yeast and some green vegetables. Although rare, vitamin B2 deficiency can occur. Symptoms include anaemia, fatigue, slowed metabolism, nerve damage, a swollen tongue, mouth sores and cracks, skin inflammation, sore throat, swelling of the mucous membranes and changes in mood.


Fast 8 - 10 hrs prior to sample being taken. Do not consume alcohol 24 hrs before test or cease prescribed medication without consulting your Doctor. Protect samples from light. Wrap in foil. Avoid coffee, tea, raw fish, liver, pork, sausage and vitamins for at least 24 hours.
