Create a simple table of two columns. The first column could be the
concentration in the desired units i.e. micrograms per litre. The second
column could be the inhibitory effect from 0% to 100%. Then you can use
VLOOKUP() to find the approximate 50% level.

You could look at Debra Dalgleish's site:

It might help with the questions caused by excel's help for =vlookup().
