LFTs Flashcards
Where in the cell and in what cell types is Apartate Aminotransferase (AST) found
RBC’s, pancreas, kidney, liver, sk mus, cardiac mus
Normal Alanine Aminotransferase (ALT) level
4-40 IU/L
Where in the cell and in what cell type is ALT enzyme found
cytosol of liver; skeletal muscle, cardiac muscle, liver tissue
Normal AST values
0-35 IU/L
Which cell types contain Alkaline Phosphatase (ALP)
Many. But think liver, bone and biliary tract epithelium
What is the normal ALP value
30-120 IU/L
How would you follow up elevated ALP level (3)
Fractionated ALP: ALP1 isoenzyme (liver), ALP2 isoenzyme (bone); GGT (if normal, then bone); 5’NT
What cell types contain GGT (Gamma-Glutamyl Transpeptidase)
many, but think hepatic and especially BILE TRACT
Normal value for GGT
8-38 IU/L lower for females less than 45 yrs
Normal Albumin level
3-6g/dL
Normal 5’NT level
0-1.6 IU/L
What cell types contain 5’NT
only liver cells
Normal Prothrombin Time
11-13 seconds
Normal Serum ammonia level
10-80 mcg/L
What is the normal total bilirubin value
0.3-1.0 mg/dL (with indirect measurement contributing the most to this value)
