Montreal: The World Anti-Doping Company (WADA) on Friday authorised an progressive technique of screening dried blood for banned substances which can be trialled for the Tokyo Olympics.
The choice marks a “essential step” within the combat towards doping, its scientific director Olivier Rabin mentioned in an interview with AFP, because the so-called dried blood spot (DBS) testing method will finally strengthen WADA’s capability to trace down cheaters.
Q. When will you begin making use of this system in a serious competitors?
A. “The Tokyo Olympics would be the first time that DBS can be utilized in a serious multisport competitors as a part of the combat towards doping… So as to not create double constraints for the athletes, the concept is that the blood that we are going to accumulate as a part of the Athlete Organic Passport, just a few drops can be taken and placed on the dry matrix (a form of blotting paper) which can permit us to analyse in a extra exact manner sure substances… At first this can be complementary to what we’re doing right now (blood assessments and urine analyses). For the Beijing Olympics subsequent 12 months, 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… It’s important to put that in parallel with the more and more elaborate doping methods of sure athletes, who know very nicely how you can use substances which keep a comparatively quick time within the physique. Sure substances, after 24, 36, 48 hours, you now not discover them… As nicely, the gathering of the pattern itself is commonly cheaper, you do not want all the standard tubes paraphernalia. And also you don’t have a bunch of bottles to retailer in massive fridges… Moderately you simply have a form of postcard that shops far more simply… As well as, it’s generally 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 essential step for the anti-doping neighborhood. Sooner or later, we will lengthen anti-doping protection, higher analyse sure substances, we will even have the ability to analyse new substances… We have to be very clear, it is not going to change the present assessments. It’s going to take a while earlier than we’ve got assessments on microliters of blood which are as environment friendly, in the event that they ever can be, as what may be finished right now with analyses of urine or bigger blood samples. However we predict that there’s a robust potential within the growth 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 right now it might not be reasonable to take action.”
