Renal function testing is important. If the patient has renal failure, the serum calcium level should be checked because hypocalcemia can exacerbate cardiac rhythm disturbances. Other tests include the following:
Electrocardiogram (ECG)
Urine potassium, sodium, and osmolality
Complete blood count (CBC)
Metabolic profile
Measurement of the trans-tubular potassium gradient (TTKG) remains widely used as a means of assessing whether decreased renal excretion of potassium is contributing to hyperkalemia. Despite its initial promise, however, recent research has called its accuracy into question, [59] and some experts now recommend that TTKG measurement be abandoned.
Depending on the clinical findings and the results of the above laboratory work, the following may be indicated:
- Glucose level - In patients with known or suspected diabetes mellitus
- Digoxin level - If the patient is on a digitalis medication
- Arterial or venous blood gas - If acidosis is suspected Urinalysis - If signs of renal insufficiency without an already known cause are present (to look for evidence of glomerulonephritis)
- Serum cortisol and aldosterone levels - To check for mineralocorticoid deficiency when other causes are eliminated
- Serum uric acid and phosphorus assays - For tumor lysis syndrome
- Serum creatinine phosphokinase (CPK) and calcium measurements - For rhabdomyolysis
- Urine myoglobin test - For crush injury or rhabdomyolysis; suspect if urinalysis reveals blood in the urine but no red blood cells are seen on urine
- microscopy
