The ADVIA 120 is a diagnostic instrument in hematology that analyzes whole blood to provide the following types of results:

 

 

A complete Blood Count (CBC) including white cell differential

and a reticulocyte count (including the absolute count and indices).

In the body fluids section of hematology, technologists examine fluids such as CSF and joint fluid for the presence of cells and correlate that information with normal values.

 

 

Joint fluids are also examined for crystals as seen in gout.

 
The coagulation division of hematology utilizes the BCS and the Electra 1600C.

Tests that can be performed include PT, aPTT, thrombin time, factor assays, etc. to check how well blood-thinning medications (anti-coagulants such heparin or coumadin therapy) are working to prevent blood clots. 

 

These tests can also be performed as part of an investigation of a bleeding or thrombotic episode or to help evaluate the risk of excessive bleeding prior to a surgical procedure.

 
Differentials in hematology are performed by a technologist and not an analyzer.

Although the Advia can perform WBC differentials, when some parameter is flagged as being out of range, the technologist must examine the blood smear under the microscope to confirm the results.  

The technologist may be looking for platelet clumps or abnormal white blood cells. When any abnormal results are seen, the technologist refers the results to a pathologist.
