Corrected Calcium
Corrected calcium adjusts total calcium for the albumin level, since part of the calcium in blood is bound to albumin.
Part of the calcium in the blood is bound to the protein albumin, so the total calcium value moves when albumin moves. Corrected calcium adjusts the reading for the albumin level with a standard formula, to show the calcium level more fairly. It is shown when albumin is outside the interval.
Everything that affects calcium or albumin affects the result. Hydration and protein intake move albumin, while vitamin D, calcium intake, some medicines such as diuretics and large supplement doses move calcium.
Foods that help
Vitamin D from sunlight, fatty fish and fortified foods, magnesium from leafy greens and nuts, and enough protein. Dairy, tofu and leafy greens provide calcium.
Foods to limit
Very large supplement doses of calcium or vitamin D, and a lot of fizzy drinks and alcohol.
