That's what all these other Lutheran denominations claim too! :)
(I don't think they all agree on their teachings, otherwise there would be only one united denomination, wouldn't there?)
If you do a quick search, you can find this list of Lutheran denominations, and it appears that there is a lot of diversity in their teachings.

List of Lutheran denominations
From Wikipedia, the free encyclopedia
"This is a list of Lutheran denominations grouped by affiliation with international Lutheran bodies. The denominations' relative size is not evident from this list. The list may not be comprehensive, but intends to be an accessible overview of the diversity and global scope of modern Lutheranism. This list does not include groups that have been merged into other groups, e.g. Hauge Synod, nor groups that have become defunct, e.g. Eielsen Synod."
