FISH or Fluorescent in-situ Hybridization is a molecular cytogenetics test that localizes DNA sequences on chromosomes with fluorescent probes. This can detect chromosomal abnormalities like microdeletions which cannot be detected by standard chromosomal analysis.

Strengths of FISH include;

  • Precise diagnosis as involves use of probes
  • A good adjunct to standard chromosomal study
  • Rapid reporting as involves no culturing of cells
  • Any cells at any stage can be tested
  1. FISH – Down’s syndrome
  2. FISH – Sex chromosome abnormalities
  3. FISH – Chromosome 18/X/Y
  4. FISH – Chromosome 13/21
  5. Aneuploidy FISH – Chromosome 13, 18, 21, X & Y

Sample Report

  1. A high resolution chromosome testing
  2. Analyzes chromosome number, shape as well as structure
  3. Genetic cause behind many abnormal physical characteristics can be determined
  4. Quick results with high sensitivity and precision

Sample requirement – 3mL blood in barcoded Sodium-Heparin sample collection tube

TAT – 3 – 5 days if all required documents are submitted on time
