standard liver panel

1. AST (SGOT)-- albumin
2. ALT (SGPT)-- total protein
3. alkaline phosphatase-- total bilirubin (from heme)-- indirect (unconj) + direct (conj)

total bilirubin elevated-- liver

Check direct and indirect bilirubin for clues
related to potential cause

other liver lab tests

1. prothrombin time (PT)
2. gamma glutamyl transferase (GGT)-- more indicative disease
(AKA: gamma glutamyl transpeptidase)
3. serum calcium: hypocalcemia-- not common, lot of things have to go wrong before
4. serum ammonia

factors contributing to hypocalcemia

decreased bile salts --> malabsorption of fat & fat soluble --> "soap formation" + reduced serum albumin + impaired vitamin D metabolism --> hypocalcemia

*insufficient intake of Ca not enough for hypocalcemia

corrected serum calcium equation

[(4 - actual serum albumin) * 0.8] + actual serum Ca
