There is a deliberate parallelism and contrast between Luke 1:41-45
and Luke 11:27-2841 When Elizabeth heard Mary’s greeting, the baby leaped in her womb; and Elizabeth was filled with the Holy Spirit. 42 And she cried out with a loud voice and said, “Blessed are you among women, and blessed is the fruit of your womb! 43 And how has it happened to me, that the mother of my Lord would come to me? 44 For behold, when the sound of your greeting reached my ears, the baby leaped in my womb for joy. 45 And blessed is she who believed that there would be a fulfillment of what had been spoken to her by the Lord.”
In all probability both passages are from the same writer.27 While Jesus was saying these things, one of the women in the crowd raised her voice and said to Him, “Blessed is the womb that bore You and the breasts at which You nursed.” 28 But He said, “On the contrary, blessed are those who hear the word of God and observe it.”
However we know that the Luke 11 passage was in Marcion's Gospel; see Tertullian Against Marcion
We also know that Marcion's Gospel lacked Elizabeth's salutation of Mary (along with the rest of chapters 1 and 2).A (certain) mother of the company exclaims, 'Blessed is the womb that bare You, and the paps which You have sucked;' but the Lord said, 'Yea, rather, blessed are they that hear the word of God, and keep it.' Now He had in precisely similar terms rejected His mother or His brethren, while preferring those who heard and obeyed God. His mother, however, was not here present with Him. On that former occasion, therefore, He had not denied that He was her son by birth. On hearing this (salutation) the second time, He the second time transferred, as He had done before, the blessedness to His disciples from the womb and the paps of His mother, from whom, however, unless He had in her (a real mother) He could not have transferred it.
If, as I have suggested, both passages are from the same writer, then Marcion's Gospel, which has one but not the other, appears to be a secondary abbreviation of the original Gospel.
