Rockville, United States, December 31: The U.S. Food and Drug Administration Tuesday approved the cobas TaqScreen MPX Test, the first nucleic acid test that screens for the presence of two divergent types of HIVdefine in donated blood plasmadefinedefine and tissue.
“With the MPX test, blood donor testing laboratories will be able to use nucleic acid technology to screen for additional HIVdefine strains, further assuring that donated blood and tissue are free from infection and providing better protection for patients,” said Jesse L. Goodman, M.D., M.P.H., director of the FDA’s Center for Biologics Evaluation and Research.
Nucleic acid is the common name for the large chemical compounds that make up the genetic material in living cells. The new FDA-approved test detects nucleic acid from HIV-2 and from HIV-1 Group O. HIV-2 infections and HIV-1 Group O infections are predominantly found on the African continent. Some cases of infection with these two types of viruses have also been detected in the United States.
In addition to HIV-2 and HIV-1 Group O, the MPX test simultaneously detects nucleic acid from the most common form of HIV, HIV-1 Group M, as well as the Hepatitis C Virus and the Hepatitis B Virus.
The MPX test is designed for use with plasmadefine specimens from human donors of whole blood and blood components, but not for testing donated source plasma. Donated source plasma is considered plasma intended for further manufacturing.
The test is also intended for screening tissue specimens obtained while the donor’s heart is still beating; it is not intended for use on specimens from donors whose heart no longer functions.
New Delhi, November 4 -- The relentless rampage of the current H1N1 monster shows no sign of abating with two more succumbing to the lethal virus Tuesday, taking the total number of fatalities in the nation to 477.
We seeks happiness even as it continues to elude many of us. However, the fact is that if we focus our attention on other things and not strive for happiness itself, we will experience this emotion more often.
