Creationists would generally agree with the above methods and use them in their geological work.

He may suggest that some other very old material had contaminated the lava as it passed through the earth.

Or he may suggest that the result was due to a characteristic of the lava—that the dyke had inherited an old ‘age’. 200.4 ± 3.2 million years) implies that the calculated date of 200.4 million years is accurate to plus or minus 3.2 million years.
