Abstract
The present disclosure relates to detection of the presence or absence of cerebrospinal fluid (CSF) in a sample by the detection of one or more antigens that are enriched in CSF compared to their levels in other bodily fluids. The devices and methods are suitable for the detection of the presence or absence of cerebrospinal fluid in samples of mixed bodily fluids from a wide variety of human populations crossing ethnicity, age, gender, health status and genetic variability.
Claims4
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.
