What was Jesus' blood type , by official pronouncement of Catholic Church?

A write-up in cherishrecatholic.org states that Jesus belonged to AB type of blood group, as per official announcement of Catholic Church. The article cites a eucharistic miracle that happened in Lanciano City, Italy in the 8th century. The Holy Eucharist, preserved since then, was examined by scientists in 1971 who determined the blood type to be AB. My question therefore is: **Has the Catholic Church officially pronounced that Jesus, in his human body, belonged to certain type of blood group?**
