Birthday girl Hodgkinson into 800m semi-final at European Indoors
The British star, who was crowned European outdoor champion over the distance last year and improved the national 800m indoor mark to 1:57.18 over the winter, turns 21 on Friday.
"It will be a nice birthday present to myself if I can defend my title," she told the BBC before adding of the weekend final: "I'm looking forward to it and hopefully I can do everyone proud."
Hodgkinson clocked 2:01.67 on Thursday in her heat.
Germany's Majtie Kolberg registered the second best time of the heats with 2:01.94. The semi-finals are on Saturday with the final set for Sunday.
Jakob Ingebrigtsen, who is chasing a 1500m/3000m double at the championships, also made it through his first test.
The Norwegian runner, Olympic gold medallist in the 1500m in Tokyo, clocked 3:50.29 over the distance on Thursday to make the next round.
It was enough for third place in his heat behind Azeddine Habz and George Mills.
Neil Gourley, who set a British record last weekend, registered the best time of the heats with 3:41.18.
Ingebrigtsen was pipped to outdoor world 1500m gold by Jake Wightman in Eugene last year, but with the Briton recovering from injury, he is a clear favourite for both golds in Istanbul.
The final of the 1500m is on Friday while the 3000m comes to a conclusion on Sunday.
