DNA microarray CGH test
This test is only available with your consultant’s referral.
Why would I take this test?
A microarray-based comparative genomic hybridisation (array CGH) is a genetic test that can investigate or diagnose medical conditions caused by missing or duplicated genes found in chromosomes.
The test is a significant development in assessing patients showing developmental delay (motor or growth), autism spectrum disorder, moderate to severe learning difficulties, dysmorphia (thinking you or your body are flawed), with or without congenital (inherited) abnormalities. Only available with your consultant’s referral.
How a test is done?
Also known as spit tests, these are very simple, non-invasive procedures. You’ll be given a small tube into which you need to ‘spit’ until it reaches a mark, and that’s it. You’ll be asked to wash your hands before handling the tube.
Fasting and special measures are required
For 30 minutes before taking the test, you must not:
eat anything
drink
chew gum
smoke
brush your teeth or use mouthwash
You should drink some water an hour so before the test, so you are hydrated.
You can continue to take regular medication but check with your doctor whether any of your medications may affect test results
