Abstract
A microscope slide having a well formed therein, wherein the well is filled with culture media. The slide is designed for on-site collection, staining, and viewing of cells in biological fluid and tissue samples, preferably with an epi-fluorescence microscope. This novel slide permits point-of-care screening in a matter of minutes of any biological fluid or tissue sample for presence of infectious agents, after which, the slide can be transported to a central lab for culture and/or definitive identification.
Claims18
A supravital microscope slide for staining a biological sample for immediate viewing with a microscope, comprising:
- a) an elongated member having a well formed therein, wherein said well is filled with solidified culture media;
- b) a supravital dye for staining the sample;
- and
- c) means for covering said well such that said dye is in contact with a surface of said culture media between said elongated member and said covering means, wherein said covering means can be removed to expose said surface of said culture media for placing the sample thereon and replaced such that the sample can be viewed under the microscope, wherein said covering means has a lower surface which abuts the sample when said covering means is replaced over said culture media.
A method for immediate, on-site screening of biological fluids for the presence of microorganisms, comprising the steps of:
- a) collecting a biological fluid sample;
- b) applying the sample to an exposed surface of solidified culture media, wherein said culture media is in a well of a microscope slide;
- c) staining the sample with a supravital dye;
- d) covering the well with a cover;
- e) viewing the stained sample to determine whether any microorganisms are present in the sample;
- and
- f) transporting the microscope slide containing the stained sample to a remote location for culture and identification of any microorganisms present in the sample.
A method for immediate, on-site screening of biological fluids for the presence of microorganisms or cellular dysmorphology, comprising the steps of:
- a) collecting a biological fluid sample;
- b) applying the sample to an exposed surface of solidified culture media, wherein said culture media is in a well of a microscope slide;
- c) staining the sample with a supravital dye;
- d) covering the well with a cover;
- and
- e) viewing the stained sample to determine whether microorganisms or cellular dysmorphology are present in the sample.
