The test on AJ Allmendinger's "B" sample has been scheduled for next week, according to the driver's management team.
Allmendinger is currently temporarily suspended from NASCAR after his "A" sample tested positive for what he has since confirmed was a stimulant. Allmendinger's test was taken June 29 at Kentucky Speedway and he was suspended July 7 when the results were received by NASCAR.
Team owner Roger Penske stated over the weekend that the team is awaiting results of this test before considering any future steps. Sam Hornish Jr. filled in for Allmendinger for the races at Daytona and New Hampshire. The Sprint Cup Series is idle this weekend.
According to a statement from Allmendinger's business manager Tara Ragan, the test will take place at 9 a.m. ET Tuesday, July 24. The test will be conducted by Aegis Analytical Laboratories in Nashville.
"Pursuant to the 2012 NASCAR Rulebook and in line with the procedures, we have elected to have a designated independent toxicologist present on AJ's behalf," Ragan's statement read. "Along with everyone else, we are looking forward to hearing the results as quickly as possible.
"AJ and all of us at Walldinger Racing have truly appreciated the outpouring of support from our fans, partners, and colleagues. It has meant a lot to us during this difficult time. We are also grateful to Mr. Penske and his management team for their patience and respect of the process we are going through."
