This Shroud, as I understand it, has been traipsed around everywhere in the hands of counts, dukes, wayfarers, circus clowns, nuns, pixies, and Martians. It's been rescued from fires, patched, handled, paraded about, stored in tombs -- anyone could have bled on the thing at any time, especially during the time or two it was rescued from fires.
Is it possible to accurately date old dried up blood with the Carbon 14
process? They claim there was type AB blood detected on the Shroud
of Turin. If it is possible, then I would think that would be the best
thing to try and date on the Shroud of Turin.
And pollen. It's been exposed to ambient air innumerable times, probably at all times of the year in all sorts of places, so pollen contamination is inevitable. I bring this up because pollen in the linen has been analyzed to death among other things.

They would have to get a sample that they are sure is entirely blood. If fibres / paint or other carbon bearing substances from a different date were included in the sample it would affect the dating method.
Originally posted by RJHindsIt could be very difficult. You cant exactly test a sample for its various elements and then later send it through the Carbon 14 test machine too. Generally, each test destroys the sample. So it would probably have to depend on visual inspection, and I am not sure that they can be distinguished that way.
