![]() For example, molecular tests for influenza can detect upper respiratory tract infections in 15 to 30 minutes. ![]() Rapid molecular tests can produce results very quickly. transcription-mediated amplification (TMA ).strand displacement amplification (SDA). ![]() nicking endonuclease amplification reaction (NEAR).loop-mediated isothermal amplification (LAMP).clustered regularly interspaced short palindromic repeats (CRISPR).Besides PCR, other testing techniques include: Other types of NAATs can help diagnose infectious diseases. PCR tests fall into a larger group of tests called nucleic acid amplification tests (NAATs). Mullis developed the PCR method in the early 1980s and won the Nobel Prize in Chemistry in 1993 for this invention. prenatal screening tests for genetic irregularities.diagnosing infectious diseases like COVID-19.The are several different types of molecular tests, such as: Molecular PCR testingĪ polymerase chain reaction (PCR) test is a specific type of molecular test used to amplify specific sections of DNA for a wide range of purposes, such as: testing for possible drug resistance in bacteria.forensic testing for identifying people for legal reasons.screening newborns for genetic conditions.neurological diseases, such as Alzheimer’s disease and Parkinson’s disease.Molecular tests have many other purposes, including: Some tests can detect more than 20 infectious organisms, such as viruses or bacteria, in about an hour. Scientists can use molecular tests to diagnose respiratory, gastrointestinal, and central nervous infections. For example, inherited changes in the genes LDLR, APOB, and PCSK9 have links to familial hypercholesterolemia. This is useful if you have genetic conditions running in your family to see if you inherited the genes. Genetic tests can look for mutations or variations in your DNA linked to the development of certain diseases. There are a variety of tests available that scientists can use to check for HPV. Molecular human papillomavirus (HPV) tests involve analyzing pieces of viral DNA to see whether they contain HPV. These tests are typically more accurate than antigen tests that look for proteins your immune system produces to defend against COVID-19. This test can better inspect pieces of the SARS-CoV-2 virus to see if you have COVID-19. Molecular testing for COVID-19 involves using a technique called reverse transcription polymerase chain reaction (RT-PCR). For example, certain changes in the EGFR gene can help doctors determine if EGFR inhibitors might effectively treat lung cancer. Molecular tests can also help identify biomarkers that suggest that certain treatments might be more effective. For example, mutations in the BRCA1or BRCA2 genes have links to hereditary breast and ovarian cancer syndrome. ![]() Molecular testing can identify genes with links to certain cancers. What is molecular testing used to determine? ![]() Using the restaurant analogy, RNA is like a copy of an individual recipe in the cookbook that each restaurant cook receives.Ī molecular test analyzes changes in these two types of molecules to look for red flags that might indicate a current or future disease. RNA is a strand of genetic material outside the nucleus that tells the functional structures in the cell what to do. If a cell were a restaurant, DNA would be like the cookbook that contains all the restaurant’s recipes. DNA is in the nucleus of every cell in your body, and its structure resembles a twisted ladder. The tissue sample might be:ĭNA comprises long strands of molecules that contain all your genetic information. Molecular testing is a field of diagnostic medicine that has undergone rapid development in recent years.Ī molecular diagnostic test analyzes the genetic information in your DNA and RNA by examining a tissue sample to look for specific disease markers. ![]()
