77021-4Fetal Y chromosome [Presence] based on Plasma cell-free DNA by SequencingActive
Part Description
LP150045-5 Sequencing
Sequencing is a method used to determine the sequence of individual genes, larger genetic regions (i.e. clusters of genes or operons), full chromosomes or entire genomes. Historically, most sequencing has been performed using the chain termination method developed by Frederick Sanger in 1977.[PMID:271968] Sequencing technologies have improved dramatically, making them cheaper, faster, and more accurate. Next-generation sequencing (NGS), also known as high-throughput sequencing, deep sequencing, and second-generation sequencing, is a type of technology that uses parallel sequencing of multiple small fragments of DNA to determine sequence. This "high-throughput" technology has increased the speed and amount of DNA sequenced at a significantly reduced cost.[PMID:18576944] Several NGS platforms (ie, sequencing instruments and associated reagents) have been developed. Third-generation sequencing is another methodology currently under development that uses parallel sequencing similar to NGS. In contrast to NGS, third-generation sequencing uses single DNA molecules rather than amplified DNA as a template.[PMID:20858600]

- First Released
- Version 2.52
- Last Updated
- Version 2.66
- Change Reason
- The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.; Added "Fetal" to Component to clarify that the result is about the fetus.
