I just got some blood and stool test results back in the mail with absolutley no explanation . Just straight test results. These were from a GI testing at a clinic in California. The test samples were tested by the Mayo Clinic. Almost all the GI tests came back negative...but there is one that says: "Immunoglobulin A." It states the "reference range" of 30-387. Then under patient ( me ) reading it says 448. This 448 number is in a column that says "out of range." I only ask because the clinic is closed at this hour and there is absolutely no comments on the 4 sheets of paper. No explanation of anything. Just staright test results. Anyone here have any idea what this may mean in any way, even general? Thanks.
