Measures B12 and folate together. Quick check when anemia, diet limits, or nerve symptoms raise deficiency concern.

Riboflavin, or Vitamin B2, is essential for maintaining vibrant health because it works closely with other B vitamins to power key bodily functions. It plays a critical role in producing red blood cells and facilitating the release of energy from the proteins you eat, supporting proper growth and daily vitality. Without sufficient Vitamin B2, people can experience cracked lips, a sore throat, or fatigue associated with anemia. This targeted blood panel measures your current Riboflavin levels, providing the information necessary to prevent deficiencies and ensure this crucial nutrient is supporting your body's energy production and overall wellness.

Vitamin B6, in the form of Pyridoxal 5'-Phosphate (PLP), is critical for over 100 essential enzyme functions, particularly those governing amino acid and energy metabolism. The Vitamin B6, Plasma test measures your PLP levels, offering a clear assessment of your nutritional status. Low levels, sometimes recognized below 30 nmol/L, are associated with serious health concerns, including an increased risk for cardiovascular disease and chronic inflammatory conditions. This test is highly valuable for anyone concerned about optimal nutrient absorption or who is managing chronic health issues, ensuring this vital cofactor is sufficient for supporting your body's energy and metabolic pathways.

Measures vitamin C in blood. Used when diet is very limited or absorption problems make deficiency plausible.
