Idowu's decision not to attend the track and field team's training camp in the Algarve has been widely criticised but the former triple jump world champion was 'disappointed and surprised' that the British Olympic Association went public with their request for him to confirm his fitness.
Idowu has withdrawn from four consecutive events since he last competed in early June and UK Athletics head coach Charles van Commenee and even Idowu's coach, Aston Moore, have admitted they have 'no idea' about the athlete's current stage of fitness.
"We are still waiting to receive the medical records from Phillips's team but we expect to receive those shortly," said Team GB chef de mission Andy Hunt.
"Once we have them we will be in discussion about any next steps.
"No-one, outside of Phillips, more wants him to compete and win a medal than us. We want him here and to be successful.
"We have top medical experts in our team and we want to give him every possible support to be successful.
“I don't think our lines of communication are poor, we have had verbal dialogue with his team. There are no hard and fast deadlines.
"Ultimately we have the right to make an assessment on selection. We have to understand the nature of the condition and then we can move to the next step.”
Meanwhile, BOA chairman Colin Moynihan insisted there was no row with the athlete, despite criticism of his organisation's behaviour from Idowu's agent.
"There is no controversy between Phillips and the BOA. But we need to know about any medical issue," he said.
"It's vitally important for the team that anything that is medically impacting on an athlete is fully known to our medical team. He's a key member of the team and we think exceptionally highly of him."
Meanwhile, team officials have confirmed that a minimum 260 athletes, from the 541 strong team, plus 40 officials will match in Friday night's £30 million opening ceremony.
Four-time Olympic champion Sir Chris Hoy will carry the British flag and the BOA are looking into flying him by helicopter from the cycling team's base in south Wales in order to have the minimum impact on his training time.
