Body Calcium

Calcium is chemical substances that form structural mineral in our bones.

Calcium is major cation in the body system.

There are many Medical Laboratory method available for the estimation of calcium levels in our body Plasma or serums.

Some among of this method depends on the precipitation of insoluble salt of Calcium.

Atomic absorption flame Photometry and Titration with Ethylene Diamine Tetraceptic Acids, (EDTA), are the most widely used method in the laboratory.

Another method which has become popular too, is Dye-Binding Method, e.g. methyl-thymol blue or cresophthalen complexone method.

Body Phosphorus

Phosphorus is chemical substances found in every body cells. Our body system contains about 17mols of phosphorus, 80 percent of the phosphorus are found to combine with bones and teeth.

The phosphorus is a constituents of many compounds which includes proteins, lipids, some coenzymes and carbohydrates.

Classification of Phosphorus in the Blood

Phosphorus in our body system are classify into four groups Which are:

1. Inorganic Phosphorus

Inorganic Phosphorus is found in the body as H2PO- and HPO4–

2. Organic or Ester Phosphorus

Organic or Ester Phosphorus are found as, glycophosphate and nucleotide phosphate.

3. Lipids Phosphorus

This phosphorus are found as Lecithin, Cephalin and Sphingomyelin.

4. Residual Phosphorus

Residual Phosphorus are found in small quantities.

Plasma contain less phosphorus compare to red blood cells. The reason red blood cells contain much phosphorus than Plasma is because it contain more ester phosphate.

Phosphorus metabolism is closely related to that of Calcium.
