Pathway Diagnostics has released its patented, second-generation SensiTrop II assay for HIV-infected patients. The product combines the sensitivity of molecular heteroduplex tracking assay technology with molecular sequencing to determine the CCR5 co-receptor tropism status of patients, according to Pathway. It provides clinicians a fast, accurate, sensitive and economical testing alternative to biological HIV tropism assay.

Oxford Expression Technologies (OET) has introduced baculoQUANT™, a novel one-step virus titration kit which can give an accurate result within 2 hours without the need for plaque assays or immunoassays. baculoQUANT™ is based on a technique called quantitative PCR (QPCR) and is a fast and cost-effective method of recombinant virus titration. This novel titration method has been proven to be a very accurate, reproducible and fast way to titrate recombinant baculoviruses1, both for single-use titrations and for high throughput applications on automated systems.

Researchers have come up with a new test that can determine whether the mother and baby are going to have different blood types or not. Published on bmj.com, the study further says that the test may substantially reduce unnecessary treatment. The baby’s blood group is predicted by typing its DNA in RhD negative pregnant women’s plasma.
