Honestly if you are born with (S.I.T) situs inversus totalis or now even Situs Ambiguus , Heterotaxy can be great indicator of the pre- exiting condition of P.C.D. Having P.C.D is malfunctioning of the cilia which translate into the listed conditions above. They are are related to organ misplacement, function and existence. Cilia development with in the fetus is like a deck of cards thrown the air and where the card land "Genetically" they land. there is no "beat " or "wave" of cilia to place such organs in there proper place or innerly the flow needed to function properly so there you have "misplacements of organs, double triple spleens or no spleens at all. I say if testing for P.C.D with these conditions may lead to answers and faster preventive care. If not born with such conditions a biopsy from the inner nose to look at the cilia there will help and of course genetic testing. Every day researchers fing more genetic sequences related to P.C.D
