Preferably, immunohistochemistry results will be very specific for a suspected condition, thereby confirming it. Even when that is not the case, immunohistochemistry can at least alter the likelihoods of different differential diagnoses. Pathology practice is too uncertain to perform calculations of exact percentages of likelihoods of differential diagnoses, but to demonstrate the general principle of how immunohistochemistry results are calculated, the following formula can be used: | Preferably, immunohistochemistry results will be very specific for a suspected condition, thereby confirming it.
