The global molecular diagnostics market size valued USD 10.92 billion in 2020 and expected to reach USD 18.6 billion by 2027, at a CAGR of 9.4% during the forecast period 2021-2027. Global Molecular Diagnostics Market are the tests that are carried out for the detection of sequences present in the DNA and RNA including deletions, insertions, rearrangements, single nucleotide polymorphism, and others for the diagnosis of diseases. Global Molecular Diagnostics Market cumulative techniques analyze the biological markers at a molecular level, like proteome and genome. Molecular diagnostics are commonly used in the diagnosis of cancer, infectious diseases, and others. These are also used in the genetic predisposition checking to a disease. Global Molecular Diagnostics Market is in the developing stage owing to increase in the prevalence of cancer, infectious disease such as HIV (according to World Health Organisation, global health observatory (GHO) data, in 2013, approximately 34-38 million people suffered from HIV infection worldwide), and hepatitis among others. A rise in research activities for the prevention of genetic disorders also fuels the molecular diagnostics market. Acquisitions & mergers, collaborations, and innovation of novel diagnostic methods are some key strategies followed by companies for increasing their revenue in the molecular diagnostics market. For instance, in August 2015, Roche Diagnostics has acquired GeneWeave Biosciences, Inc. for strengthening its portfolio in microbiology diagnostics. Moreover, in April 2015, Alere Inc. received FDA approval for Alere I Strep, a molecular diagnostic test for the detection of Group A Streptococcus bacteria.
