Buckingham Palace announced on Wednesday morning that she had canceled a planned trip to Northern Ireland because her doctors advised her to take a day off.
But after the newspaper The Sun wrote about it, the royal house had to admit on Thursday night that she had taken some samples in hospital and stayed there overnight.
She returned to her residence at Windsor Castle from the private King Edward III Hospital in London on Thursday morning, according to the royal family “in good spirits”.
The news agency Press Association writes that the hospital stay was not announced because it was expected that it would only be a short stay. She stayed overnight for “practical reasons” because it was too late to drive the 42 miles back to Windsor.
Author Robert Hardman tells the BBC that there will probably be some annoyance at the castle over the news coming out, because they are concerned with “preserving the queen’s dignity”.

But the BBC’s royal reporter Nicholas Witchell says that the royal house has not given a complete picture of the situation, and that rumors and speculation are therefore swirling.
