What We Test
Common vitamin and nutrient blood tests.
Vitamin D
Helpful for bone health, muscle weakness, low sun exposure, fatigue or low bone density concerns.
Vitamin B12
Important for nerves and blood cells. Low levels may be linked with tingling, weakness or balance concerns.
Folate
Often checked with B12, especially when anemia, high MCV or pregnancy-related planning is relevant.
Iron / Ferritin
Low iron stores may cause fatigue, dizziness, shortness of breath or poor exercise tolerance.
CBC Pattern
Blood count helps connect vitamin or iron results with anemia patterns.
Related Markers
Thyroid, liver, kidney or inflammation tests may be added depending on symptoms.
Who Should Consider Testing
Testing is useful when symptoms and risk factors match.
Low Sun Exposure
Indoor work, winter season, covered clothing or little outdoor time may affect vitamin D status.
Vitamin D
Vegetarian / Vegan Diet
B12 can be lower when animal-source foods are limited.
B12
Fatigue + Abnormal CBC
