简介：

Overview

High resolution melting analysis (HRM) is a rapid method for detecting genetic variants, particularly effective in identifying calreticulin mutations in patients with hematologic conditions. This technique combines HRM with agarose gel electrophoresis to distinguish various genetic variants.

Key Study Components
