A member asked:
Last 12 months had a potassium blood test each month and it was always 4.2. how is it so consistent with the exact same number?
A doctor has provided 1 answer
A bit mysterious: People are generally not so consistent that they have a 4.2 result twelve times in a row. Of course, the numbers are mathematically rounded off, so that 4.2 actually is a range from 4.15 to 4.25. However, if any of one's other lab results, or anything else seems odd, the patient can review the whole year's results with his primary care doctor.
