entsprechender Verdacht

13:26 Nov 9, 2009 

As I noted in Johanna's answer, I believe that indication is a step further. Suspicion is not yet confirmed ( obviously) and an indication arises after a diagnosis [based on a prior clinical suspicion] has been confirmed. Usually, indication is used when administering therapy.
That being said, however, I agree that a "relevant indication to perform the test" could work too, from a medical linguistic standpoint, yet I believe that that would change the original a bit.
Thus, I feel that in this case "relevant clinical suspicion" may indeed work best. As for leaving out the entsprechend part, I think that it is not really needed. However, if we can translate it, why not do it? "Relevant" or even "reasonable" as Zareh suggested, would work. They're just trying to differentiate between the unfounded and founded suspicions. For instance, a junior medical student may have a suspicion, a far shot, so in this case one would not administer the test as the suspicion was not founded/relevant/reasonable.

Johanna's suggestion does away with "entsprechend". What do others think about this? Otherwise I like "indicated".
