Abstract

Methods of estimating chromosome band resolution have been published but their accuracy has not been established. Banding resolution was determined by 4 methods which included a computerized linear correlation, the sum of bands on chromosomes 1 and 2, interpolation of the number of bands on chromosome 10, and interpolation of the number of bands on chromosomes 1p, 10, 11p, 12q, and X. The sum of bands on chromosomes 1 and 2 multiplied by 6 is the most accurate and simple. The use of a simple and reliable method is important for cytogenetic laboratories to document quality assurance of routine chromosome analyses, to enhance the exchange of information between laboratories, and to establish criteria for appropriate band resolution for specific types of specimens.
