What is a DNA Microarray Test?
A DNA Microarray Test is a cutting-edge genomic technology designed to analyze thousands of genes simultaneously with high precision and speed. Unlike traditional PCR or qPCR, which examines a limited number of genes, microarray technology can detect multiple genetic variations, gene mutations, and expression patterns on a single platform.
Microarray testing is commonly used in research, clinical diagnostics, and personalized medicine to understand genetic influences on health, disease, and treatment response.
How Does DNA Microarray Testing Work?
DNA microarrays consist of thousands of spots on a solid surface (usually glass), each containing identical DNA sequences representing a specific gene. The testing process involves:
- Sample Collection: DNA or RNA is extracted from the patient’s blood or tissue.
- cDNA Preparation: RNA is converted to complementary DNA (cDNA) using reverse transcription.
- Labeling: The cDNA is labeled with fluorescent markers for detection.
- Hybridization: Labeled cDNA is applied to the microarray chip, binding to complementary DNA strands.
- Data Analysis: Fluorescence patterns indicate gene expression levels or genetic variations, which are analyzed using specialized software.
This method enables high-throughput analysis of thousands of genes in a single test, providing a comprehensive overview of genetic activity.
Types of DNA Microarray Tests
- Microarray Mutation Analysis:
Detects single nucleotide polymorphisms (SNPs) and genetic mutations using genomic DNA (gDNA). - Microarray Gene Expression Analysis:
Measures the activity of genes derived from mRNA in normal vs diseased tissues to identify overexpressed or underexpressed genes. - Comprehensive Genomic Analysis:
Detects increases or decreases in chromosomal fragments to assess genes involved in diseases.
Benefits of DNA Microarray Testing
- Detects genetic mutations and SNPs accurately.
- Screens thousands of genes at once, saving time compared to traditional testing.
- Provides valuable insights for diagnosis, treatment planning, and research.
- Non-invasive and suitable for clinical and research applications.
