Colorimetric screening method for microalbuminuria: intra-individual variability for untimed day specimens.

is similarly variable in the human brain, then this variation must be the first consideration in any attempt to estimate brain lesion size. This requires that the lesions must be clearly defined by region. One might expect the direct correlation of brain lesion size in humans with any serum CK isoenzyme values to be of little value until more is known about the distribution of these enzymes in human brain and how they are released.
