Uric Acid (Urine) Blood Test Marylebone

Who considers Uric Acid (Urine)

• People often consider kidney tests if they have high blood pressure or diabetes, both of which place the kidneys under long-term strain.
• Regular use of anti-inflammatory painkillers, lithium or certain blood pressure tablets is a common reason to monitor.
• Swollen ankles, foamy urine or passing water more often at night may prompt a check.
• Those with a family history of polycystic kidney disease or kidney failure frequently want a baseline.
• It is included in most general health screens and before starting some medicines and supplements.

What Uric Acid (Urine) measures

The catalogue tags the Uric Acid (Urine) with gout, kidney function and hyperuricemia. Those terms describe the territory the test covers; the notes below explain what a kidney function and electrolytes result can and cannot tell you.

Kidney tests measure waste products the kidneys clear — creatinine and urea — and use creatinine, age and sex to estimate filtration rate (eGFR). Electrolytes such as sodium, potassium, chloride and bicarbonate show how well fluid and acid–base balance is being maintained, and cystatin C offers an alternative filtration marker less affected by muscle mass. Urine albumin-to-creatinine ratio, when added, looks for early protein leak.

Understanding your Uric Acid (Urine) results

A high creatinine or low eGFR can indicate reduced filtration, though a single value in a muscular person or after dehydration may overstate the problem. Potassium and sodium outside their ranges are taken seriously because they affect heart rhythm and fluid balance, and the laboratory may telephone the clinic if a value is markedly abnormal. Trends over time matter more than a single snapshot, so previous results are useful.
