Claim One:
1. A device for detection of the presence or absence of cerebrospinal fluid in a sample, comprising a sample application region, a sample labeling region comprising a first antibody to a CSF-enriched protein, wherein the first antibody is conjugated to a mobile particle; a sample detection region comprising a second antibody to the CSF-enriched protein, wherein the second antibody is fixed to the sample detection region, wherein the presence of a detectable band in the sample detection region indicates the presence of cerebrospinal fluid in the sample, wherein the CSF-enriched protein is selected from the group consisting of CNTN2 Contactin-2 precursor (SEQ ID NO: 3; Accession Number gi|4827022); cDNA FLJ59893, dickkopf homolog 3 precursor (SEQ ID NO: 13; Accession Number gi|40548389); CADM3 Homo sapiens cell adhesion molecule 3 (CADM3), transcript variant 1 (SEQ ID NO: 17; Neural cell adhesion molecule variant (SEQ ID NO: 19; Accession Number gi:62088238); a CSF-enriched phosphorylated or dephosphorylated form of the foregoing CSF antigens; and a combination of two or more of the foregoing CSF antigens.
