Figure 4.13 Differential Counter


The system will automatically assign the corresponding initials of the employee, signed on or if Order Entry Security is used, the employee assigned to the password used, to the Result field of Order Entry Maintenance screen.


Once this is entered, the differential screen displays. This display contains the patient's demographics and the current and previous CBC values for this order if performing a differential on a CBC.  If a differential is being performed on any other procedure that does not contain result fields listed next to Current: and Previous:, these fields will be blank. In addition, the keyboard settings displayed are specific to the employee signed on provided that set up was performed in the Laboratory Control Record for the employee. If not set up per employee, the displays the default keyboard settings.



From the Diff Counter menu, the following selections may be made:


Start Count


This selection will clear any differential values and allow the differential to be counted. Each keystroke of the displayed character will count the corresponding cell type and display the additive total. The Total field will accumulate the total for all cell types counted except NRBC (nucleated red blood cell). If an invalid character key is pressed, no counting will occur. When 100 WBCs have been counted, the system will stop the count.


Continue Counting - This selection is used when more than 100 cells need to be counted or after correcting a cell count. The system will allow counting cells and will stop when the count has reached 200. If more cells need to be counted, the option may be selected numerous time but each time the counting will continue until the next 100 cells are counted.  


STOP Count - This selection stops the counting process and may be used whenever the user needs to momentarily stop the counting process, or to stop the counting process and choose one the appropriate options listed above to exit the screen.
Correcting Count during Differential Counting: When in the course of counting, an error has been made, select STOP Count. The value entered in any of the cell-count fields may be changed by highlighting the value, making the change, and pressing the tab or the enter key. When this occurs, the total will be adjusted with each change.


Exit - Comp - This selection will complete the order and will apply the system date/time and the initials in the Complete field.


Exit - Incomp - This selection will exit to the Order Entry Maintenance screen without completing the differential.


Exit (NO Save - This selection will exit the Differential Counter without retaining any entered data and will take the user back to the Order Entry Maintenance screen.


Next Diff - This selection will prompt for an order number allowing easy access to the next patient's differential.


Correct WBC - This selection will correct the WBC for any cells counted as NRBC's. This option's functionality is based on the specified number of NRBC's defined in the Laboratory Control Record.


Percentages - When selected prior to Start Count, this option will automatically compute and display cell percentages during the counting process, or if not chosen prior to Start Count, the user selects the STOP Count, this may be selected and the percentages will be displayed.


Prev CBC - When selected, the system will display the last previous CBC and manual differential (if performed) for this patient's account number.


Format - Inc -This selection will return to the report format so that any changes or additions to the report may be made (e.g.: to enter abnormal red cell morphology). When zeroing out of the result screen, the system will not apply initials/date/time to the Complete field.


Format-Comp - The selection will return to the report format so that any changes or additions to the report may be made (e.g.: to report abnormal red cell morphology). When 0 (zero) is entered from the report format, the order is completed and the system date, time, and initials are applied.
