Calcium Lab Test Interactions

Calcium's effect on lab tests
Calcium has an effect on the following lab tests:
- Serum hydroxycorticosteroid
Serum (blood) concentrations of hydroxycorticosteroid can be elevated when calcium supplements are taken over a long time and at high levels. These class of medication deplete calcium levels in the body - Serum phosphate (phosphorus)
Serum (blood) concentrations of phosphate (phosphorus) may be reduced when calcium supplements are taken over a long time and at high levels.
Serum (blood levels) of hydroxycorticosteroid may be elevated when calcium supplements are taken at high levels and over a long period
Other interactions with Calcium
Calcium also has interactions with the following substances:
- Alcohol
Alcohol can decrease the absorption and increase the elimination of calcium, so it could cause a deficiency that will require supplementation if the alcohol intake is excessive and over a long term. - Caffeine
High intake of caffeine (from coffee, tea, soft drinks and chocolate) can reduce absorption of calcium, so eat foods high in calcium (or take calcium supplements) at least an hour or so before having any caffeine containing drinks or food.
