examines gene expression levels across thousands of genes simultaneously

Microarray Analysis, also known as Gene Chip Analysis or DNA Microarray Analysis, is a laboratory technique used to study the expression levels of many genes simultaneously. It involves placing thousands of DNA sequences on a small chip, then exposing it to a sample to see which genes are active or inactive. This method is particularly useful for understanding complex genetic conditions, such as alopecia, by identifying which genes are involved in the disease process.
