FDA Approves Rapid Ebola Test, Drastically Reducing Diagnosis Time

Posted byBy S.C Rhyne | Published on: CommentsComments (0)

The U.S. Food and Drug Administration has approved a rapid diagnostic tool for Ebola screening.

The Swiss pharmaceutical company, Roche, announced on Monday that its test is approved for emergency use only, meaning that some labs in the United States and abroad can use it for a restricted amount of time but it’s not yet available to the general public.

LightMix Ebola Zaire rRT-PCR Test can detect the virus in about three hours; the standard Ebola tests can take about a day.

The test looks for a specific pattern in the messenger ribonucleic acid (mRNA); these molecules carry genetic information from the DNA to inside the cells. The test interprets the genetic material on this mRNA strand to the corresponding DNA strand and then millions of copies of the DNA strand is made so the clinician can see whether this particular DNA strand is that of the virus. The test uses a process called a polymerase chain reaction to copy the DNA over and over again.

The acronym, RT-PCR, stands for reverse transcriptase polymerase chain reaction. “The LightMix’s fast turnaround allows healthcare professionals to quickly detect the virus and start patient treatment as early as possible,” said Roland Diggelman, COO of Roche Diagnostics Division, to Fortune.

Lightmix is one of the diagnostic tools approved by the FDA in 2014 as the ebola epidemic still ravages West Africa and is a great concern all over the world. Currently, the World Health Organization reports that total number of known and suspected cases surpasses 20,000 and known and suspected deaths from the disease climb towards 8,000. The numbers are most likely an underestimate of the true damage.

Thus, Roche’s new diagnostic test means that treatment can be available to patients earlier, however the test must still be performed in a lab. For tens of thousands of Africans living in remote villages with little infrastructure, it’s not clear how this breakthrough can help curb the epidemic.

Democracy needs journalism it can trust.

This election season, the stakes are higher than usual — and so is the pressure on newsrooms to soften their coverage, stay quiet, or just disappear. Independent reporting, the kind that answers to readers instead of advertisers or political pressure, matters more in a moment like this, not less.

For over 14 years, Atlanta Black Star has stayed independent and reader-funded. We have no corporate owner and no shareholders telling us what to cover or how to cover it. That independence is also our biggest vulnerability: nothing protects it except readers choosing to fund it directly.

Newspaper ad revenue has fallen more than 80% since 2005, and local newsrooms are closing at a rate of roughly two a week nationwide. When outlets go under in a moment like this, it's rarely the independent, reader-funded ones that get to stick around.

We know a request for support isn't why you came here. But without readers choosing to fund this work directly, the depth of reporting we can do at home and abroad shrinks along with everyone else's. If you're not in a position to give, that doesn't change how much we value you as a reader.

If you are able to, a recurring contribution does more for us than a single one-time gift, because it lets us plan the next investigation instead of just the next invoice. It takes about 30 seconds, no long form, no account. Thank you for continuing to support independent journalism and freedom of the press.
