Range?
Measures?
Examples? - correct answer0-139 units/L
Muscle Injury. muscle enzyme found in skeletal and cardiac muscle;
elevated blood levels associated with heart attack, muscular dystrophy, and other
skeletal muscle pathologies
Urea Nitrogen (BUN)
Creatinine - correct answer8-20 mg/dL
0.6-1.2 mg/dl
Kidney Function
Increased in impaired kidney function
Measured with lithium therapy
Creatinine is more sensitive and specific indicator of kidney disease than BUN.
Measured with lithium therapy.

Range?
Measures?
Examples? - correct answer>90mL/min.
The best measurement of kidney function.
the amount of filtrate formed per minute by the two kidneys combined
Elderly pts have 30% reduced because of decreased muscle mass
Generally no dose adjustments or contraindications with psychotropics when GFR
>60mL/min
Valproate and select epileptic drugs ex. Carbamazepine.
Lab testing?

Discontinue when? - correct answerLiver pane (ALT, AST, ALP, bilirubin, albumin, total
protein), CBC, WBC, platelet count, serum hCG, valproate level.
Level 50-120mcg/ml
Discontinue valproate with AST/ALT elevations >2-3x upper limit of normal.
Valpro ate a folate PLaTe

Comment?
What meds to avoid? - correct answerCreatine, bun, GFR, TSH, serum electrolytes,
CBC, hCG, urinalysis.
Baseline EKG
Check serum lithium level 12 hour post dose (trough) after 4 days in medication. Then
every 4-5 days.
Lithium level 0.6-1.2
