Claim One:
1. A method for detecting the presence or absence of cerebrospinal fluid (CSF) in a sample, comprising: obtaining the sample suspected of containing CSF from a subject; applying the sample to a lateral flow immunoassay device for detection of the presence or absence of CSF in the sample, wherein said device comprises a sample application region, a sample labeling region comprising a first antibody to a CSF-enriched protein of SEQ ID NO: 13, wherein the first antibody is conjugated to a mobile particle, and a sample detection region comprising a second antibody to the CSF-enriched protein of SEQ ID NO: 13, wherein the second antibody is fixed to the sample detection region, and wherein, when the sample contains CSF, said device displays a detectable band in the sample detection region, wherein the presence of the detectable band in the sample detection region indicates the presence of CSF in the sample.
