Dear friend, welcome to HCM.
I feel there is nothing to worry.
mild decrease in red cell parameters is not very bad. may be anaemic trend.
is not mentioned.
units are?? if it is 1.04mg%, it is normal. what are its normal units written for that lab?
but anyway, I see no alarm, if creatinine values convert to ~ 1.04mg% or mg/ decilitre
take care and keep me posted on your progress.
