I have the last couple of days have seen many people who are upset because their friend may not be a test for the coronavirus, even though they are experiencing flu-like symptoms, or have been on a skiing holiday in the Alps. This is a great example of the Limits of a time that helped Erlander catch up with the ”rising expectations the dissatisfaction of the” People believe that the authorities ' clumsy sopprötter for less than three months after the discovery of the virus is not capable of testing large segments of the population are in favour of it. Confidence in the medical ability to juggle with my knees is, obviously, great.
the Difficulties with the new version of Coronavirus is, as we all know, the new one. Really, really quick testing at a large scale, you can make a micro-organism, after isolation, it is, learned how to grow it in a fairly large scale, cast in dead microbe into the animals and allowed animals to move around, for a sufficient time to form antibodies against the microbe.
For example, you may squirt it with a lot of horses, and after a month or so to begin to purify the antibodies from the horse blood, and then to design and refine a method for using the antibody to detect the virus in samples taken from the patients.
It goes without saying that some of these tests have not been developed. And, in addition, such tests are not really suitable for the diagnosis of the virus in the respiratory tract, because they have the risk of missing out on the kind of virus.
Take the time to calibrate it
Fortunately, there is another way to test for the virus, which is based on a complex and störningskänsligt way to bring in some of the virus's genetic material is copied so much, and then detecting the hordes of replicas, as it is easier to detect than that of a single cell. These tests will take less time to develop, and are able to start designing as soon as you have the virus's genetic material is known, which, as we have for more than a month's time.
this is a complex and sensitive issue, and will take the time to re-calibrate in order to get a reasonable control over the risks associated with both missed a virus in which it is found, and to give a false alarm. As it is, it is a relatively personalintensivt to carry out the tests, and it is only possible to test a limited number of samples in parallel. When such a method is to set up a new lab, it takes time to test that it is working as it should, despite the fact that it has made a dramatic shortcuts on the procedures that would normally be used for the validation of new test methods.
increase in Capacity
I have been in early life worked in the training of biomedical analysts, in-the theory behind it, and the principle of these tests, and are constantly talking to people who are using these methods in both the clinical laboratory and in research. I'm fascinated by how quickly it's gone now, from the genetic material of sekvenserades for the exam is available in a number of laboratories in the country. We are able to test out of one hundred samples per day, and capacity is constantly increasing.
This is a result of the bioteknikernas great deal in the past few decades, do not clutter. Do we see ourselves in the world, Sweden is at the forefront of the capacity of the test samples (although not primarily). The republic of korea stand out, with a capacity of one order of magnitude above our own, but they came to hire out the analysis for a broad range of private labs that have set up the analysis very quickly. Microbiologists I have talked to wonder about those labs indeed had the necessary quality control measures.
we are forced to give priority to
of Course, it would have been nice if it was possible to test for the virus is – both from the smittskyddssynpunkt, in order to allay any unnecessary concerns, and a lot of the important scientific questions about the behavior, should be dealt with.
" But when we count the number of tests that can be done on a per-day, in a growing number of hundreds, then it goes without saying that priority should be given to those who are most likely to carry the virus. It is not possible to test all of that land at the Airport, or get a cold. < / span> < / span>
