DIFFERENCE BETWEEN GENETIC SCREENING & GENETIC TESTING
GENETIC SCREENING Genetic screening is the procedure of screening an individual in order to identify the health status of the individual and to find out does the individual comes under the category of high risk category patients. The screening process does not guarantee 100% accuracy in its results. It’s just like a practice of check-up in order to understand abnormalities in genital health.
WHY GENETIC SCREENING ●
Genetic screening is mainly undergone by individuals who are more prone to genetic disorders as a cause of inheritance or hereditary.
●
Also patients who feel instability and abnormality in their health may undergo as a part of health check up to know their genital health status.
GENETIC TESTING Genetic testing is a medical diagnosing testing that involves analysis of human DNA through which identification of mutations in DNA sequence or chromosome structure can be known. Mutations in the DNA sequence can be a clear indication of physical deformity or chances of getting high risk illness in future. Genetic testing conducts diagnosis of the genetic disorder with high accuracy and precision.
WHY GENETIC TESTING ●
Genetic testing is one of the best ways of diagnosing deadly diseases at the earliest.
●
As this testing process gives the correct gential health status, it is easy to know the body disorder even if the symptoms are not physically expressed.
GENETIC DISORDERS These are some of the common genetic disorders that are diagnosed through genetic testing procedure ● ● ● ● ●
Albinism Angelman syndrome. Cystic fibrosis (CF) Down syndrome. Thalassaemia Sickle Cell Anaemia
HOW TESTING IS CONDUCTED ● ●
The genetic material for testing is collected through blood smear. Also by taking cheek swab or through amniocentesis for pregnant womens, the testing can be done.
CONCLUSION Thus it’s clear that genetic testing is a process of diagnosing the metabolic genetic disorder within the human body with much precision and accuracy. The purpose of genetic screening test is to determine which individuals may have a higher risk factor for the disease or disorder. Screening does not determine a diagnosis. .
