Haven't lived in Sweden for 35 years, so not familiar with that. A web search found https://1177.se , is it that?
We also have it in Finland as https://kanta.fi. You can see all your healthcare visits, but only short summaries. Results from examinations are not there. Got the analysis of my last blood samples on paper. But that was a friendly doctor, often you get nothing. I think legally you have the right to get everything, not sure, haven't been ill... But you'd need to request it and there is no standardized way to do so regardless of healthcare provider.
