A couple of months ago I had a renal panel blood draw. The results from LabCorp came back with a very low EGFR. The score showed a 20% decrease from the same test a year ago. I commented my concerns to my doctor. He recalculated the score using the National Kidney Foundation calculator. The score he calculated showed no degradation from the previous year. I then went to an independent test site and had another renal panel blood test done. The results came back identical to the calculated score from the doctor. The work by LabCorp is incompetent at best.
Recommendation: Don't trust results from LabCorp.
