About kidney (renal) function testing in Vashon

Home to roughly 10,886 people, Vashon is a smaller community in Pacific. Coastal metros, inland towns, and rural counties with very different access to testing — worth weighing when you schedule a visit.

Rather than calling around, compare tests here, then arrange a draw in the Vashon area when it suits you.

Orders are handled confidentially: your details stay private and results are released through a secure portal. Because individual sites vary, double-check the lab's own guidance on preparation, timing, and cost.

What it measures

  • Creatinine — A waste product from muscle that healthy kidneys remove. Higher levels can mean reduced kidney function.
  • Blood urea nitrogen (BUN) — Another waste product from protein breakdown. Levels can rise if kidneys are not filtering well.
  • Estimated glomerular filtration rate (eGFR) — A calculated number based on creatinine that estimates how much blood your kidneys filter per minute.
  • Electrolytes (sodium, potassium, chloride, bicarbonate) — Minerals that help your body work. Kidneys balance these, so abnormal levels can signal kidney issues.
  • Calcium and phosphorus — Minerals linked to bone health. Kidneys help regulate them, so changes may reflect kidney function.

Preparation

Fasting is usually not required for a kidney function panel, but your provider may ask you to fast if other tests are done at the same time. Drink water normally unless told otherwise.

Results and what they mean

Results are reported as numbers for each substance, often with a reference range. Your clinician interprets them based on your health history, medications, and other tests. This is general information, not medical advice; only a qualified professional can diagnose or treat any condition.
