Muco-viscidosis

Detection of specific proteins in the meconium of babies8. The presence of these proteins can be an indication for muco-viscidosis. Owing to limited precision and accuracy, however, if the test is positive, further experiments should be carried out before a diagnosis is made. 

A second test, also suffering from poor precision and accuracy, is a blood test, done a few days after the baby s birth9. The presence of relatively high concentrations of immuno-reactive trypsine is an indication for muco-viscidosis. In this case also, further investigations should be carried out prior to formulation of the diagnosis.
