Question

Two women put claim over a child as mother; which test can prove this claim to be true ?
1. Vidal Test
2. Tuberculin Test
3. D.N.A. Test
4. ELISA Test

Answer 1

Correct Answer - Option 3 : D.N.A. Test

The correct answer is D.N.A. Test.

• Two women put a claim over a child as a mother; the D.N.A. test can prove this claim to be true.
• Genetic testing is also known as DNA testing and is used to identify the changes in DNA sequence or chromosome structure.
• Genetic tests are performed on a sample of blood, hair, skin, amniotic fluid, or other tissue.

• Types of genetic tests are:
  • Newborn screening - This is used just after birth to identify genetic disorders that can be treated early in life.
  • Diagnostic testing - This is used to identify or rule out a specific genetic or chromosomal condition.
  • Carrier testing - This is used to identify people who carry one copy of a gene mutation that, when present in two copies, causes a genetic disorder.
  • Prenatal testing - This is used to detect changes in a fetus's genes or chromosomes before birth.
  • Preimplantation testing - This is also called preimplantation genetic diagnosis (PGD), is a specialized technique that can reduce the risk of having a child with a particular genetic or chromosomal disorder.
  • Predictive and presymptomatic test - This type of testing is used to detect gene mutations associated with disorders that appear after birth, often later in life.
  • Forensic testing - This is used DNA sequences to identify an individual for legal purposes.

Test	Details
Vidal Test	Widal test. Purpose. serological test for enteric fever. In 1896 and named after its inventor, Georges-Fernand Widal, is an indirect agglutination test for enteric fever or undulant fever whereby bacteria causing typhoid fever is mixed with a serum containing specific antibodies obtained from an infected individual.
Tuberculin Test	The TB skin test is performed by injecting a small amount of fluid (called tuberculin) into the skin on the lower part of the arm.
ELISA Test	An enzyme-linked immunosorbent assay, also called ELISA or EIA, is a test that detects and measures antibodies in your blood. This test can be used to determine if you have antibodies related to certain infectious conditions.
