Example text

In this case study2, Mr and Mrs Roothaan are confronted with an ambiguous result: a finding that may or may not indicate a specific problem. Actually, it is a preliminary or ‘grey’ result, one of which it is still unclear whether it will turn out to be normal (‘white’) or aberrant (‘black’). This kind of result is a common phenomenon in prenatal diagnosis. Chromosome investigations may produce a black result in line with the reason for doing the test (usually Down’s syndrome), other black results, and also different kinds of grey results (see Box 1).

The result is not really bad, as there is no evidence of Down’s syndrome. Its possibility, after all, because of Mrs Roothaan’s age, provided 17 18 Genetics from Laboratory to Society the principal reason for chorionic villi sampling. On the other hand, the result cannot be 100 per cent good, since they have to see the clinical geneticist. In this case study2, Mr and Mrs Roothaan are confronted with an ambiguous result: a finding that may or may not indicate a specific problem. Actually, it is a preliminary or ‘grey’ result, one of which it is still unclear whether it will turn out to be normal (‘white’) or aberrant (‘black’).

Additional investigation of the chromosomes in other types of cells thus allowed for turning a grey result into either a white one or a black one. Both possibilities were found in the observed testing trajectories: some grey preliminary findings became black results and others changed into 26 Genetics from Laboratory to Society white results. , a combination of a normal cell line and a cell line with trisomy 21) recorded in the short-term culture of the chorionic villi sampling turned black once a full trisomy 21 was found in the long-term culture.
