What does this mean?
I just looked at the last 3 times I've had bloodwork done and all 3 times showed low MCH, high RDW.
In addition to those two showing up on every set of bloodwork, these were flagged:
Oldest Bloodwork (2 years ago): Low WBC, Low MCV,
Second (1.5 years ago): Low WBC, Low MCV, Low neutrophils.
Newest (2 weeks ago): High RBC, Low MCHC
None of this was far outside of the range, but it was flagged.
But, what causes this?
I've been a varying version of paleo for over 3 years. Everything that was flagged on the tests I have listed, except for some cholesterol numbers (my LDL tends to be a bit high).
Specific Numbers: MCH: 25.6, 25.9, 25.2. RDW: 15.3, 15.6, 16.1

RDW (Red cell Distribution Width or something, it comes from a graph) just means there are two different sizes of red blood cells, usually normal and either macro or microcytic. Yours are probably normal and micro since you had a low MCV (Mean Cell Volume) previously, but really, RDW doesn't mean much until you get to 20+. It's nothing to be concerned about on it's own.
MCHC (Mean Cell Hbg Concentration) is the amount of hemoglobin in your RBC, usually. There are external factors(lipemic blood, cold agglutigens, or a certain cell shape) that can skew the MCHC, but those cause false increases, not decreases.
MCH doesn't mean much. We don't pay attention to it, no matter how it flags.
I wouldn't be concerned with any of these results. Maybe, you might have a bit of an anemia (low MCHC=lower hgb, low MCV= smaller cells), but don't lose sleep over it.
