Claim 13:
14. The method of claim 1, further comprising empirically determining the predetermined cutoff value beforehand by (a) running a plurality of samples on the lateral flow device of human serum diluted 90× to 110× with a buffer solution from a previously-undiluted serum sample previously obtained from one or more humans, wherein the serum samples do not contain CSF, and calculating the optical value for each of the plurality of samples from (T1 intensity)2×(T2 intensity), and (b) running a plurality of samples on the lateral flow device of human serum diluted 90× to 110× with a buffer solution from a previously-undiluted serum sample previously obtained from one or more humans, wherein the serum samples do contain CSF, and calculating the optical value for each of those plurality from (T1 intensity)2×(T2 intensity), wherein steps (a) and (b) can be performed in any order, and (c) selecting an optical value, as the predetermined cut off, which optical value is (i) in excess of every one of the calculated optical values for each of the plurality of samples in step (a) which do not contain CSF, and (ii) is below every one of the calculated optical values for each of the plurality of samples in step (b) which do contain CSF, so as to determine the predetermined cutoff value.
