| 摘要 |
The invention provides an assay for diagnosing and/or monitoring a viral infection or disease in a patient, the assay including the steps of mixing a sample of leucocytes with a fluorescent cell membrane-permeable dye which stains RNA or both DNA and RNA within the leucocytes; identifying from all the leucocytes at least two of the three major sub-populations of leucoytes selected from the group consisting of monocytes, granulocytes and lymphocytes; determining the fluorescence intensity for each of the identified sub-populations; and comparing the fluorescence intensity of at least two cell sub-populations to each other to obtain at least one of the following ratios: monocytes:granulocytes, monocytes:lymphocytes, and granulocytes lymphocytes. The viral infection may be HIV and the disease may be AIDS. The invention also provides a method of monitoring the cellular viral, parasitic or bacterial reservoir of a patient with a viral or bacterial infection by the steps described above. A, kit for performing the assay or method is also provided.
