Overview
In a patient who does not have a risk for hyperkalemia, repeating the blood test is indicated before taking any actions unless changes are present on electrocardiography.
Laboratory Findings
In a patient who does not have a risk for hyperkalemia, repeating the blood test is indicated before taking any actions unless changes are present on electrocardiography.
Initial tests
- Complete blood count (CBC)
- Metabolic profile
- Urine potassium, sodium, and osmolality
Cause specific
- Blood glucose In patients with history of diabetes mellitus
- Digoxin level
- Arterial or venous blood gas (acidosis)
- Urinalysis (renal insufficiency)
- Serum cortisol and aldosterone levels (mineralocorticoid deficiency)
- Serum uric acid and phosphorus assays (tumor lysis syndrome)
- Serum creatinine phosphokinase (CPK) and calcium measurements and urine myoglobin test (crush injury or rhabdomyolysis)
