Montreal: The World Anti-Doping Company (WADA) on Friday permitted an modern technique of screening dried blood for banned substances which will likely be trialled for the Tokyo Olympics.
The choice marks a “crucial step” within the combat in opposition to doping, its scientific director Olivier Rabin mentioned in an interview with AFP, because the so-called dried blood spot (DBS) testing approach will in the end strengthen WADA’s capability to trace down cheaters.
Q. When will you begin making use of this method in a significant competitors?
A. “The Tokyo Olympics would be the first time that DBS will likely be utilized in a significant multisport competitors as a part of the combat in opposition to doping… So as to not create double constraints for the athletes, the thought is that the blood that we are going to gather as a part of the Athlete Organic Passport, just a few drops will likely be taken and placed on the dry matrix (a sort of blotting paper) which is able to permit us to analyse in a extra exact method sure substances… At first this will likely be complementary to what we’re doing at the moment (blood assessments and urine analyses). For the Beijing Olympics subsequent yr, there’s a development deliberate, we are going to combine new analyses.”
Q. What are the advantages?
A: “To start out with it is much less intrusive for the athletes. Some samples are taken from the fingertip, from the earlobe, from the shoulder, from the thigh… The opposite benefit of DBS is that from the second you place it on a chunk of paper, the liquid will dry and it stabilises the matrix… You need to put that in parallel with the more and more elaborate doping methods of sure athletes, who know very properly methods to use substances which keep a comparatively brief time within the physique. Sure substances, after 24, 36, 48 hours, you not discover them… As properly, the gathering of the pattern itself is usually inexpensive, you do not want all the standard tubes paraphernalia. And also you should not have a bunch of bottles to retailer in giant fridges… Fairly you simply have a sort of postcard that shops rather more simply… As well as, it’s typically tough to go and take (conventional) samples in distant areas which are removed from our anti-doping labs.”
Q. Is that this new technique a “sport changer,” as AMA President Witold Banka has predicted?
A. “This can be a crucial step for the anti-doping neighborhood. Sooner or later, we will lengthen anti-doping protection, higher analyse sure substances, we may also be capable of analyse new substances… We should be very clear, it is not going to substitute the present assessments. It’ll take a while earlier than we’ve assessments on microliters of blood which are as environment friendly, in the event that they ever will likely be, as what will be completed at the moment with analyses of urine or bigger blood samples. However we predict that there’s a robust potential within the improvement of such a matrix. Possibly in 5 years, 10 years, we will measure EPO in just a few microliters of dried blood, during which case we are going to say: that is it, we will apply DBS to EPO, however at the moment it will not be reasonable to take action.”
