Have the values from Froome’s other tests during the 2017 Vuelta been made available?
To Froome, UCI, WADA & Glaxo of course, that's what they used to determine the PK Study wouldn't be useful as his declared Salbutomol use was not just one day like a swimmer. We know how many times he was urine tested, because he was race leader stage 3-21 and CADF test the leader of the race after every stage. So Froome has a 'known' continuous daily record of 19 doping controls in La Vuelta with a corresponding declaration of medication and amounts attached to them. All controls will be urine with a beta-2 level, blood & bio passport in addition on some days too.
Reading the comments above on his inhalation record could just be fabricated, while true to some extent, Froome (or his Dr) does have to declare his beta-2 use & the amounts taken on his doping control form each of the 19 days of controls. It's pretty clear those assumptions above by red_flanders are made not having any idea of how a doping control form works or what is filled in by the athlete/his doctor in reality. We can however, at least assume that at the time of giving his beta-2 declaration (if Salbutomol used that day) existed 19 times in a row, Froome doesn't know he would AAF on one of them. He can't possibly know what his corresponding urine level reading would be against that declaration either as he's only just finished the stage. It would be extremely easy to determine his declared use didn't match the levels found in his urine across those 19 days or had consistency to catch Froome out imo. This was the weakness in Ulissi's case - he didn't declare use and he didn't know how much he inhaled either, although his use was only one day only iirc, so PK Study was used.
Doping Control Form
3. INFORMATION FOR ANALYSIS
DECLARATION OF MEDICATION USE AND BLOOD TRANSFUSIONS: LIST ANY PRESCRIPTION / NON-PRESCRIPTION MEDICATIONS OR SUPPLEMENTS, FOR E.G. BETA-2 AGONISTS AND GLUCOCORTICOIDS, TAKEN OVER THE PAST 7 DAYS (INCLUDE DOSAGE AND DATE LAST TAKEN WHERE POSSIBLE) AND (IF A BLOOD SAMPLE IS COLLECTED) ANY BLOOD TRANSFUSIONS RECEIVED OVER THE LAST THREE MONTHS.
So we can safely assume he has a complete inhalation record with corresponding urine level 'known' by WADA, UCI, himself & Glaxo and this is what Dr Austin said he modelled against known human pharmacology for Salbutomol use.
