When your level reads http://>60/ml/min/1.73^2, does this mean that it is greater than 60 but less than the next measured value such as 90? Or does this mean greater than 60 so could be as high as 110? Thanks for helping me understand this range by Lab Corp. Also protein is 8.3, so my understanding is that it is in the normal range by 1 point. Would you be concerned or get rechecked?

The estimating equations that we use to estimate the glomerular filtration rate (eGFR) are more accurate for an eGFR of less than 60 milliliters per minute per 1.73 meters squared.  Hence, values that are above 60 are deemed to be normal, as our ability estimate eGFR above 60 is not as exact as we would hope.  The estimating equations can tell the difference in eGFR’s between 60 and 90 but likely cannot reliably tell the difference between 90 and 110.

If you have risk factors for chronic kidney disease (CKD), then annual testing for CKD using blood tests and urine tests is important and recommended.
