From the cut segment, measuring 81 x 21 mm, a stripe showing coloured filaments of doubted origin had to be discarded.The remaining sample, measuring 81 x 16 mm and weighing 300 mg, was first divided in two equal parts, one of which was cut in three.On September 28, 1988, British Museum director and coordinator of the study Michael Tite communicated the official results to the Diocese of Turin and to the Holy See.

Professor Gian Marco Rinaldi shocked the academic world by claiming that Kouznetsov never performed the experiments described in his papers, citing non-existent fonts and sources, including the museums from which he claimed to have obtained the samples of ancient weaves on which he performed the experiments: the actual standard deviation for the Tucson study was 17 years, not 31, as published; the chi-square distribution value is 8.6 rather than 6.4, and the relative significance level (which measures the reliability of the results) is close to 1% - rather than the published 5%, which is the minimum acceptable threshold. Sue Benford proposed that the sampled area of the cloth may have been unoriginal (none of the sample contained a "stained" area), as almost 60% of the cloth is because of the progressive repairs throughout the centuries.

Conspiracy theorists have proposed that the published results are, in fact, reflective of the control piece dating back from the 14th century, insinuating that the labs would have (perhaps unwittingly) "mixed up" the samples and produced a final report predicated on analyses conducted on the wrong piece of cloth. Scholar Raymond Rogers argued, in a 2005 article, that the chemical analysis he performed confirmed this hypothesis - as the samples used in the carbon-dating show evident traces of tanning products, likely used by medieval weavers to match the colour of the original weave when performing repairs and backing the shroud for additional protection.

This "leak", along with the violations to the protocol, marred the credibility of this phase of the procedure and fed suspicions of tampering.

The blind tests were called a "staging" by Evin and a "façade for public opinion" by Tite.

Also present were cardinal Ballestrero, four priests, archdiocese spokesperson Luigi Gonella, photographers, a camera operator, Michael Tite and the labs' representatives (who, according the protocol, should in fact not have been present).

As a precautionary measure, a piece twice as big as the one required by the protocol was cut; the unused half was preserved in a sealed container, in case of need.

The reportage, broadcast late July, asserted that the shroud was, in fact, medieval, before tests had begun at the lab at Oxford's.
