Molecular testing, or molecular diagnostics, are a group of tests that takes a deep dive into the genetic material in any specimen. The kind of testing helps in detecting genetic risk factors for certain diseases and also offers evidence of any infections in the body.
As the name suggests, this kind of testing detects and amplifies the visibility of molecules in samples. These samples usually come from blood, saliva, and biopsy. In most of the contexts, molecular testing offers greater precision. A simple example is, a doctor using such type of testing to determine the specific genetics of a type of a cancer, so that he can suggest a better line of treatment for the patient.
How does molecular diagnostic work?
As soon as a sample goes for molecular testing, the testing will look for segments into DNA or RNA associated with specific health conditions.
The testing is performed in critical cases because the results are quite accurate. In many cases, molecular testing can also offer certainty to a diagnostic of a person.
The testing uses several techniques to detect the presence of the targeted genetic material in a cell, and each procedure shall work differently. Some techniques used in molecular testing are:
- fluorescent in situ hybridization (FISH)
- chromosomal microarray analysis
- cytogenetic analysis or karyotyping
With each technique, the doctor will collect a sample from the body and will process it further to make the molecules more visible. If you are looking for molecular diagnostic low-cost provider, you can reach out to us. We will be glad to assist you.
