It said there were suspicions that the students had contracted food poisoning.
The governor of Assiut, meanwhile, has referred the case to prosecution authorities for investigation.
The governor accused the Muslim Brotherhood, the movement to which ousted President Mohamed Morsi belongs, of standing behind the apparent mass food poisoning with the aim of causing tension inside the university.
No case of food poisoning has been officially registered yet, the dormitory's medical administration said in a statement.
A Health Ministry official in Assiut, however, said that around 150 university students had been taken to four hospitals after experiencing food poisoning.
"Samples were taken from the students and sent to the central labs of the Health Ministry in Cairo to see whether there was food poisoning or not," Ahmed Abdel-Hamed, an undersecretary at the Ministry of Health in Assiut, told The Anadolu Agency.
Food poisoning has become a common occurrence at Egypt's universities in recent years.
In April of last year, hundreds of students experienced food poisoning in two separate incidents in Cairo after eating meals at their university dorm.
