DNA Genetics screening overview

dna genetics testing

DNA (deoxyribonucleic acid) carries the genetic information in the body’s cells. A gene is a distinct portion of a cell’s DNA. Genes are packaged in bundles called chromosomes. A genetic disorder is an illness or condition caused by abnormalities in your genes or your chromosomes.

There are many types of genetic tests or screenings available, the most common being:

  • Gene carrier testing to examine a person’s DNA to ascertain if they are a carrier of a faulty gene or carry a faulty gene which can be subsequently passed on to future generations.
  • Chromosome testing to examine for the presence of abnormal chromosomes most commonly found in and associated with the unborn baby.

Gene Carrier testing

DNA tests are available to help a couple determine if they are carriers of a genetic disorder trait and are at risk of having children with that condition.

Screening is broadly divided into four groups, depending on the timing of the testing:-

  • testing of couples or individuals before pregnancy (adults)
  • antenatal (during pregnancy)
  • neonatal (in the newly born)
  • older children

Chromosome screening

This is my offers a range of tests for peace of mind for chromosomal conditions.

Sometimes the screening process is worrisome. Many women receive unnecessary high-risk results and the waiting is worst of all. We aim to strip away all the confusion about screening and provide you with the safest, most accurate and advanced chromosomal screening services available so that you can relax, feeling fully informed and confident that you made the right choice.
