Rapid Test For Ebola Now Available

Posted by Soulskill on from the for-when-you-might-have-ebola-on-the-go dept.

sciencehabit writes: The World Health Organization (WHO) has approved the first rapid diagnostic test for Ebola. The test needs no electricity, requires just a few drops of blood from a finger prick, and can return results in 15 minutes. That will be a huge help to health workers in remote areas. Current PCR-based tests require a blood sample taken by needle, secure transport of the blood to a properly equipped laboratory with trained staff, and at least several hours to return results. Depending on how far away a suspected case is from a testing laboratory, it can take more than a day to receive test results.

      Yeah, or maybe it's because this outbreak killed more people than all previous outbreaks combined. For example this report from 2003 lists 128 total deaths in a remote area of the Congo, at the peak of this outbreak there were more people than that dying per day in Sierra Leone. It's pretty understandable that you don't spend billions on research and development for a drug that might be used on 40 people per year on average but would on a drug that can stop a global pandemic.

      Modern Healthcare Algorithm:
      First there will be the cheap/rapid initial screening test with high sensitivity and low specificity. Next comes the validation test with slightly higher specificity, slightly more expensive. If the result is still positive, after that a series of more expensive confirmatory tests will need to be performed. If an arbitrary number of confirmatory tests agree with each other, then the diagnosis can be made. If the diagnosis is made, then first the quickest/cheapest treatment will be applied (that has low probability of success). If the initial treatment fails, more complicated and expensive measures will be tried, with higher probability of success. If those fail, extremely expensive experimental treatments with unknown (possibly 100%) probability of success may be attempted.

      Wouldn't we expect that to occur in the absence of an outbreak? Fewer people are dying in areas where fewer people live does not surprise me. I have a theory that the number of deaths (d) cannot exceed the number of people (n). Stated mathematically dn. In addition, it is likely that d is proportional to n, so d=p*n where p is a proportionality constant that can be estimated from data. We would need to collect data from various times and regions to get a sense of the stability of p.

      Not so much me thinks.

      A test and or a tester is very different than a cure or immunization for Ebola.
      The ability to further screen someone identified by a remote non touch fever
      sensor is the gold here.

      Hospitals had issues sorting 80 some common infections that presented like Ebola.
      The only unique Q&A answer that identified Ebola as a likely infection was "did you travel to _Africa_?".

      Should Ebola have surfaced with a vengeance in one or more modern cities the options that
      health departments have are few. One is to isolate the city and divide it while Ebola burns itself out.
      The collapse of commerce for food and other common needs would be difficult to sort out.

      And more importantly because this is not a treatment the testing and approval time frame
      could be very short. And more importantly there are cities in Africa that could use it now.

      There are some social implications but from the containment side of the option list
      this is a good thing.

    The new test, produced by Corgenix, a company in Broomfield, Colorado, uses antibodies to identify a specific Ebola virus protein.

But discounts will be available, he says, for bulk purchases and suppliers for use in Africa.

      Here's what I'm guessing: in practical terms the test in question won't tell you any more than your bleeding eyeball test would, if we're talking about people with obvious hemorrhagic fever symptoms who have recently spent time in an Ebola hot zone.

      The reason that something like this is needed is that *early* symptoms of Ebola are pretty much identical to influenza or any number of other viral illnesses. So you have someone coming from Liberia with the flu, you give them the quick finger stick test and send them on their way if it's negative. If it's positive you isolate them and perform an expensive, time-consuming "gold-standard" test like PCR or neutralization.

      And in case anyone is wondering, using a test like this for screening asymptomatic people coming from Ebola areas would almost certainly be futile. If there's no symptoms yet there won't be enough antigens to trigger an antibody test like this. At present there's no test that will catch recently infected people who aren't showing symptoms. Anyone exposed to Ebola have to monitor themselves for fever for a few weeks.
