(CNN) -- Caster Semenya has been left out of South Africa's squad for the African Athletics Championships, which take place in Kenya from July 28 to August 1.
The 19-year-old world 800m champion has not raced since undergoing tests to determine her gender.
However, she has already stated she intends to compete in a meeting in Zaragoza, Spain on June 24, although that will be dependent on the result of the tests -- which were first expected to be released last November.
Despite not being named in the 57-strong squad, Athletics South Africa (ASA) assistant administrator Richard Stander has insisted the list is not final and is only preliminary.
"The list is not final," Stander told Press Association Sport. "The criteria is very clear, the athletes that have performed in the last couple of months have been put in the squad.
He continued: "Even though Caster was one of those names not on that list, she is one of quite a number of athletes who will have to prove themselves during a six-week window period prior to the final squad deadline on July 6.
"It doesn't help setting the qualifying standard six months before the event. If an athlete can't reach the same standard shortly before the championships, then they're not ready to compete at international level," added Stander.
