calcium in serum corrected for albumin

Reference interval

• Male & Female: 8.1 - 10.9 mg/dL (same as for serum calcium)

Principle

• see calcium in serum

Clinical significance

• in the circulation Ca+2 is
  • bound to protein (45%)
  • in the free ionized form (45%)
  • complexed to anions (10%)
• albumin is the major serum protein binding Ca+2
• reference intervals for serum Ca+2 assume a normal serum albumin
• a 'corrected' Ca+2 (for diminished albumin) may be estimated by the equation:

Corrected Ca+2 = 0.8 x (4 - [[[A13149|serum albumin]] (g/dL)]) + serum Ca+2

Specimen
