Not entirely sure what it is you want, so if I understand correctly, you want besides the variable that is already in there, a variable that only holds a certain value if that row is that test.
Is this correct?
If there is not too many types of results, you could just write an if-function.
if (material = "Blood" & Parameter = "Sodium") SodiumBlood = result.
if (Parameter = "Hemoblobine") Hemoglobine = result.
