The Osmolality Blood Test measures the concentration of dissolved particles such as electrolytes, glucose, and urea in blood. It helps evaluate hydration status, kidney function, and electrolyte balance. Doctors use this test to investigate hyponatremia, dehydration, poisoning, or metabolic disorders. Abnormal levels may indicate impaired kidney regulation, diabetes insipidus, or toxin exposure, guiding diagnosis, treatment, and monitoring therapy effectiveness.

Patient must be 18 years of age or older

The Sodium Test measures sodium levels in the blood, an electrolyte essential for fluid balance, nerve function, and muscle activity. Abnormal sodium may indicate dehydration, kidney disease, adrenal disorders, or heart failure. Doctors use this test to investigate symptoms like confusion, weakness, or swelling and to monitor patients with chronic illnesses, diuretic use, or intravenous therapy, ensuring proper electrolyte and metabolic health.
