The Supreme Council of Antiquities (SCA) decided to conduct laboratory tests on one of the unknown mummies in the tomb of King "Citi I" with the purpose of determining whether it belongs to the King Thutmose I or not. This came after the mummy believed to be of King Thutmose I withdrawn from the Royal Mummies Hall in the Egyptian Museum as archeologists discovered that it is not his mummy.

Dr. Zahi Hawwas, SCA Secretary General, said on 3/7/2007 that the DNA analyses on the unknown mummy will be compared to the analyses made on the members of the family of the king including Hatshepsut, Thutmose II and Thutmose III. Hawwas added that after archeologists have confirmed that the mummy of King "Thutmose I" is not for him following the DNA analyses, the mummy withdrawn from the Royal Mummies Hall in the Egyptian Museum and a specialized Egyptian team of archeologists and technicians will start search for the mummy of King Thutmose I.

It is noteworthy that upon Thutmose I's death, the throne passed to his son Thutmose II who married his sister Hatshepsut, daughter of the main wife of King Thutmose I, in order to support his right in the throne but Hatshepsut, who gave birth to only one female baby namely Nefro Ra, took over the throne instead of Thutmose III, son of his husband, who was a little child (boy) and had herself crowned pharaoh "Queen" and took male titles and appearance.
