Brown suffers from complex regional pain syndrome - giving her chronic pain in her feet - but World Archery said it did not impact on performance.
Danielle Brown facts
Born: 10 April, 1988
Took up archery aged 15 after her medical condition left her unable to run.
Made GB debut at 2006 European Championships
Won individual compound gold at 2007, 2009 and 2011 World Championships
Won Paralympic compound gold in 2008 and 2012

The governing body has acknowledged an appeal by Brown and she will be re-tested in Lilleshall in February.
"We are delighted that Danielle will have this opportunity," Archery GB performance director Sara Symington told BBC Sport.
"We continue to support Danielle in and way we can and remain hopeful that following this re-classification she will be allowed to continue competing."
Following World Archery's ruling in November, Archery GB - the UK's governing body - was forced to put Brown on a four-month notice period.
It means that unless she can secure a reprieve, the London gold medallist will leave the British programme and lose her UK Sport funding in early March.
Brown, who competes while seated on a stool to relieve the pain she experiences when standing, said in a statement late last year that she was "bitterly disappointed" with World Archery's decision to bar her.
"My disability affects my life in every way and archery is the one thing that has kept me going," she said.
"It is extremely difficult to hear that the classifiers believe my disability doesn't impact my sport as it impacts every part of my life, including archery."

World Archery will soon appoint two independent assessors - who have not previously worked with Brown - to conduct the re-classification.
They will assess her range of movement and medical records before delivering their verdict later in February.

Brown will compete for the first time since learning of her Paralympic ineligibility at the European Archery Festival in Telford 24-26 January.
