About Genetic Testing
What is it? Why it is required? These are a few of the questions that novice people are likely to ask. Genetic testing is generally used by doctors to identify defective or missing genes in the patient. Availing this crucial information does help the doctor to know if the patient, his/her partner as well as their baby might suffer from certain medical conditions. Identifying the issues much early through this testing process does allow the patient s well as the immediate family members to get proper and correct treatment.
Genetic tests can be termed to be body tissues or small blood samples that get analyzed at the lab setting. There can be used different kinds of body tissues and fluids. The genetic test type required to diagnose any ailments depends on the type of condition that the doctor checks for.
Why carry out genetic testing of the pregnant mother?
Doctors do recommend the pregnant woman to get genetic testing. A blood test is carried out to screen the pregnant woman to find out if she is suffering from some medical disorders. If the blood test screening process reveals some medical issues, then the doctor could recommend chorionic villus sampling or amniocentesis.

- CVS (Chorionic villus sampling): This is generally performed during the pregnancy stage around 10 to 12 weeks. In this type, the doctor eliminates a small placenta piece to diagnose genetic issues if developed in the fetus region. Chorionic villus sampling being an invasive test might pose a small risk. It might induce miscarriage.
- Amniocentesis: This test is generally performed as the woman reaches stage 15 to 20 weeks of pregnancy. In this type, a hollow needle is inserted within the woman’s abdomen to remove amniotic fluid, but in small amounts from the surrounding region of the developing fetus. The doctor then evaluates the fluid to identify genetic issues as well as to determine the child’s gender status. In case of premature birth risk, carrying out this test shows maturity level of the baby’s lungs. But this test also comes with some risk of miscarriage.
Why Genetic Testing is favoured & recommended by doctors?
The qualified doctor might recommend Newborn Genetic Testing or counselling for several reasons.
- Standard prenatal screening exam provides abnormal results. The doctors might suggest genetic testing in case, potential genetic problem is identified in the screening test.
- Pregnant woman has crossed 34 years of age. In such cases, chances are that the child born to such woman may suffer from chromosomal problems like trisomy. Even children born to older fathers may develop risks of dominant genetic mutations. It might be the result of any single genetic defect something that the family has never witnessed before.visit here to know more information : jio rockers.com
- The parent might have already given birth to a child, but having serious birth defect. According to medical experts not all children exhibit genetic issues if having birth defects. At times, exposure to infection, toxin (poison), or even physical trauma arising before birth might result in birth defect. The cause, at times might not be known. If the child suffers from some genetic issues, then it could possible not be inherited. A few cases might arise from spontaneous errors caused in the child’s cells and not that of the parents’ cells.
- The couple have plans to expand their family, but one of them or some close relative is known to have inherited illness. A few people are found to be genes carriers for genetic illnesses. But they might not display illness signs themselves. This could be since a few genetic illnesses are stated to be recessive in nature. It means, symptoms are noticed only if two copies are inherited by the person of the genetic defect, from each parent. Again children inheriting a single genetic defect from a single parent and another normal one from the other parent do not exhibit recessive illness symptoms. However, 50% chances are there of passing down the defect gent to the children.
- The woman might have given birth to a stillborn child showing genetic illness physical signs. Most serious genetic illnesses might result unique and specific physical problems.
- The woman might have had a couple of miscarriages or even more. Severe chromosome problems taking place in the fetus region might result in spontaneous miscarriage. This can perhaps be some genetic issue.
- Child exhibiting medical issues considered to be part of some genetic syndrome. By carrying out genetic testing on the child, diagnosis is possible. It may also help identify the severity type of genetic illness. Doctors can use the reports to prescribe the best possible treatments.
- The child might suffer from genetic related medical problems. The health problems could probably involve several body systems. Through genetic testing, doctors may identify the cause as well as make proper diagnosis.
Genetic treatments have improved with time and are a hope to cure many genetic problems.
