What usually happens next

Most often it simply means you drank a lot before the test.

If your urine stays this dilute with large volumes even when you drink little, your doctor may check how your kidneys concentrate urine.

When a urine specific gravity can read wrong

A first-morning sample is the most concentrated of the day. Glucose, protein and X-ray contrast in the urine push the number up without you being dehydrated.
