What is genetic testing?
Genetic testing is a type of medical test that identifies changes in genes, chromosomes, or proteins. The results of a genetic test can confirm or rule out a suspected genetic condition or help determine a person’s chance of developing or passing on a genetic disorder. More than 77,000 genetic tests are currently in use, and others are being developed.
Genetic testing involves looking for changes in:
Genes: Gene tests study DNA sequences to identify variations (mutations) in genes that can cause or increase the risk of a genetic disorder. Gene tests can be narrow or large in scope, analyzing an individual DNA building block (nucleotide), one or more genes, or all of a person’s DNA (which is known as their genome).
Chromosomes: Chromosomal genetic tests analyze whole chromosomes or long lengths of DNA to see if there are large genetic changes, such as an extra copy of a chromosome, that cause a genetic condition.
Proteins: Biochemical genetic tests study the amount or activity level of proteins or enzymes; abnormalities in either can indicate changes to the DNA that result in a genetic disorder.
Genetic testing is voluntary. Because testing has benefits as well as limitations and risks, the decision about whether to be tested is a personal and complex one. A geneticist or genetic counselor can help by providing information about the pros and cons of the test and discussing the social and emotional aspects of testing.
Geneture provides one stop solution of Nucleic Acid Extraction and Analysis. There are several kinds of nucleic acid extraction kit, including Animal Genomic DNA Nucleic Acid Extraction Kit, Plant Genomic DNA Nucleic Acid Extraction Kit, Bacterial Genomic DNA Extraction Kit, Whole Blood Genomic DNA Nucleic Acid Extraction Kit and so on. These kits use magnetic beads to adsorb DNA/RNA to achieve the purpose of rapid DNA/RNA purification. It is suitable for extracting high-purity DNA from samples (grinding supernatant of animal and plant tissues, whole blood, serum, plasma, cell culture supernatant, oral pharyngeal swabs, body fluids, genital secretions, bacteria and viruses, etc.) /RNA, used for molecular biology experiments such as PCR/RT-PCR, Real-time PCR/Real-time RT-PCR.
These kits are used for nucleic acid extraction, enrichment, purification and other steps, and the processed product can be used for clinical in vitro testing. Please contact us if you need more information about the genetic testing.
