Abstract

A method of performing a first analysis and a second analysis on a single blood sample obtained with a single blood draw from a patient with an automated analyzer includes the steps of supplying the single blood sample obtained with the single blood draw from the patient to the automated analyzer. A memory on the automated analyzer containing a software routine is automatically accessed. The software routine is useful to adapt an optical system on the automated analyzer to correspond to the first analysis and the second analysis. The optical system on the automated analyzer is automatically adapted with the software routine in real time to correspond to the first analysis. The first analysis is automatically performed with the automated analyzer. The optical system on the automated analyzer is automatically adapted with the software routine in real time to correspond to the second analysis. The second analysis is automatically performed with the automated analyzer.

Dependent claims

A fully automated cell analysis method of performing a first cell analysis and a second cell analysis on a single blood sample obtained with a single blood draw from a patient with a fully automated cell analyzer comprising a flow cell required to perform the first cell analysis and the second cell analysis, the method comprising the steps of:

(a) supplying the single blood sample obtained with the single blood draw from the patient to the fully automated cell analyzer;
(b) automatically accessing a memory on the fully automated cell analyzer containing a software routine, the software routine being useful to adapt an optical system optically connected with the flow cell on the fully automated cell analyzer to correspond to the first cell analysis and the cell second analysis;
(c) automatically adapting the optical system on the fully automated cell analyzer with the software routine in real time to correspond to the first cell analysis;
(d) automatically performing the first cell analysis with the fully automated cell analyzer by passing at least one cell in a first portion of the single blood sample obtained with the single blood draw from the patient through the flow cell;
(e) automatically adapting the optical system on the fully automated cell analyzer with the software routine in real time to correspond to the second cell analysis;
and
(f) automatically performing the second cell analysis with the fully automated cell analyzer by passing at least one cell in a second portion of the single blood sample obtained with the single blood draw from the patient through the flow cell.
