Automation technologies represent a fundamental aspect of any modern industry. The major types of industrial automation solutions, such as DCS, PLC, SCADA, and MES, are used on a large-scale in process and discrete industries.DCS technologie Awhile ago, I got an email from one of the "gurus" I follow and it shocked me. The gist of it was this person wanted to trade services for a household item.To say it floored me would be an understatement.What was worse was a few days later t
Prenatal testing constitutes the second fastest growing area of genetic testing worldwide. In addition to being the largest market for prenatal screening globally, North America is also likely to record the fastest CAGR of 18.1% during the similar period. The major purpose of prenatal testing is to detect the alterations in a fetus’ genes or chromosomes prior to birth. This testing has been recommended for couples having a pronounced risk of giving birth to a baby with a genetic or chromosomal disorder. Prenatal testing, in certain cases, can be helpful in reducing a couple’s uncertainty or in coming to a decision to abort the pregnancy. However, this test has been found lacking in identifying all possible birth defects and inherited disorders.Prenatal tests are very helpful, however, most important is to interpret the results. A positive test result doesn’t always mean that the baby will be born with a disorder. It is important to take help from a healthcare expert on the results obtained.Prenatal tests are not completely reliable and are not available for every possible inherited disorder. Genetic testing cannot always provide a definitive answer, and it is possible for test results to show false negatives, positives or return as variants of unknown significance. Another thing to think about is the possibility that the test results are wrong. A false negative result happens when a genetic test has failed to detect a certain allele or faulty chromosome. It means test has not produced DNA differences in the results looking for inherited disorder. It does not mean there won’t be chance of developing inherited disorder, but it only means that another version of the gene is present for this inherited disorder.According to CDC, Birth defects affect 1 in 33 babies born in the United States each year and can occur at any point during pregnancy, but most of them take place during the formation of the baby's organs, which is the first trimester of the pregnancy.Most Common type of Prenatal Genetic Tests are invasive and require cells which are extracted from the fetus. Chorionic Villus Sampling (CVS) and Amniocentesis are the common prenatal tests. CVS is usually done at 10-12 weeks of pregnancy and involves taking a sample of cells from placenta. According to Mayo Clinic, CVS has 1% risk of miscarriage. Amniocentesis is usually done at 15-20 weeks of pregnancy and involves extracting sample from the amniotic fluid.A new prenatal screening test, called cell free fetal DNA testing, done at 10 weeks of pregnancy, uses the mother's blood to detect Down syndrome. This procedure is not covered by the insurance companies. The current state of the non-inclusion of all genetic tests in reimbursement has hampered the growth of genetic testing market across the globe. In most countries, a specific regulation for the reimbursement of comprehensive exploration of an individual’s genome is not in place. A few laboratories in Europe have already been accredited for NGS applications, including exome sequencing (for targeted analysis), even if no clear guidelines or consensus criteria exist.Title XVIII of the Social Security Act, Section 1862(a) states “No Medicare payment shall be made for items or services which are not reasonable and necessary for the diagnosis and treatment of illness or injury". Furthermore, a longstanding CMS policy states, "tests that are performed in the absence of signs, symptoms, complaints, or personal history of disease or injury are not covered unless explicitly authorized by statute".
