Sorry, I forget who the doctor was, and I'm not familiar with the
subject.  For what it's worth, I'm pretty sure it wasn't Covert Bailey,
Andrew Weil, or Nicholas Perricone.

Incidentally, /The Merck Manual 16/ contains an extensive list of
laboratory normal ranges in its "Special Subjects" section.  They're the
ones used at the Massachusetts General Hospital and published in NEJM.

Here's an excerpt:

 Determination         Reference Range

 Protein: Total        6.0-8.4 gm/dL
   Albumin             3.5-5.0 gm/dL
   Globulin            2.3-3.5 gm/dL
       Note: Globulin equals total protein minus albumin.
   Electrophoresis     % of total protein
       Note: Quantitation by densitometry
     Albumin           52-68
     Globulin:
      alpha-1          4.2-7.2
      alpha-2          6.8-12
      beta             9.3-15
      gamma            13-23

I wouldn't give it a second thought, frankly.  Perhaps you could find
out how variable it usually is from hour to hour, assuming it depends on
meals, exercise, sleep, growth, etc., but why distrust your doctor?

To me, the surprising thing is that it's the only measurement that was
out of range.  Of ten independent tests, assuming the normal range is
from the 5th to the 95th percentiles, you'd expect one to be out of
range anyway, if I understand the math, and it was very close.
