Christine Ohuruogu will test her fitness at the London Grand Prix on 28 July before deciding whether to run at August's European Championships.
Ohuruogu remains uncertain about a European tilt
The Commonwealth 400m champion has been struggling with a sore Achilles tendon and will only take her place in the Great Britain squad if fully fit.
"We are going to use the race to prove my fitness," Ohuruogu told BBC Sport.
"Then we can measure where I am in terms of fitness and whether it would make sense for me to go to Gothenburg."
Ohuruogu ran a brilliant race in Melbourne to claim Commonwealth gold in a personal best time of 50.28 seconds.
The 22-year-old Londoner also stunned Olympic and world champion Tonique Williams-Darling, pushing her into second place.
I just want to get through the race feeling OK
However, Ohuruogu has not ran a competitive 400m since and looked rusty running over 200m at the European Trials in Manchester, where she finished fifth.
Instead, she has been nursing a persistent Achilles injury while continuing to train at her east London base.
Ohuruogu makes her comeback amidst a high-qualify field at the Norwich Union London Grand Prix , which includes Williams-Darling and American Sanya Richards, the fastest woman over 400m this season.
But the Commonwealth champion insists she will be racing her own race at Crystal Palace next Friday.
"Everyone keeps saying, 'how are you going to cope next week?'", said Ohuruogu.
"What people need to realise is that the athletes I am up against have a lot of races under their belt and so are race-fit, whereas I am not.
"My expectations are totally different to theirs. I just want to get through the race feeling OK.
"I also want to use it as a time trial to assess how fit I am. My rehab has been going well and the injury is feeling a lot better.
"I'm confident my Achilles will hold up but there's only one way to find out if it doesn't."
