Comprehensive blood test analyzing Vitamin D, B12, and Iron levels relevant to thyroid health.

Additional Information

This panel measures Vitamin D, B12, and Iron levels, crucial for thyroid function and overall health. Vitamin D aids calcium absorption for bone health, B12 supports nerve and red blood cell function, and iron is essential for red blood cell production. Imbalances in these nutrients can impact thyroid function and cause various symptoms. This test helps identify deficiencies or excesses, guiding personalized interventions.

Biomarkers Tested (6)

Active Vitamin B12 (pmol/L)

Active vitamin B12 is the biologically active form of vitamin B12 that is essential for many physiological processes in the body, including the production of red blood cells, DNA synthesis, and nerve function.

Vitamin D (25-OHD) (ng/mL)

Although called a vitamin, vitamin D (25-OHD) is actually a steroid hormone which is activated by sunshine on the skin. It is essential for bone strength as it helps the intestines absorb calcium.

Iron (µg/dL)

Iron (Fe) is essential for hemoglobin production and oxygen transport. Low levels can lead to anemia, while high levels may indicate iron overload disorders.

Transferrin (mg/dL)

Transferrin is a protein that binds and transports iron in the blood. Abnormal levels can indicate iron metabolism disorders.

Transferrin saturation (%)

Transferrin saturation measures the percentage of transferrin bound with iron, indicating iron status. Abnormal levels can indicate iron deficiency or overload.

Ferritin (ng/mL)

Ferritin is a protein that stores iron in the body. Low levels can indicate iron deficiency, while high levels may suggest iron overload or inflammation.
