FIT screening

The FIT-based screening test is easy and therefore manages to attract high participation rates – the main driver behind the success of any national or regional screening programme. Generally, national or regional administrations assume responsibility for managing the logistics, financials and efficiency of the programme in close cooperation with their selected laboratory partners.

Immature Granulocyte (IG) count

What is an IG count?

With the exception of blood from neonates or pregnant women, the appearance of immature granulocytes in the peripheral blood indicates an early-stage response to infection, inflammation or other stimuli of the bone marrow. Being able to detect them quickly and reliably opens doors to new diagnostic possibilities for related disorders.

Current areas of research regarding the diagnostic significance of circulating immature granulocytes focus on the early and rapid discrimination of bacterial from viral infections, particularly in children, recognising bacterial infection in neonates, and the early recognition of bacterial infection and sepsis in adults, which is of vital importance in particular for intensive care patients.

Valuable information for immediate action – at no additional cost

 

IG counts are relevant especially for patients who are highly susceptible to infections because of a suppressed immune system and because the increased IG count indicates the severity of the early innate immune response. In addition to patients with general infections and inflammations, clinicians will pay particular attention to:

  • Patients from the intensive care unit,
  • Patients undergoing chemotherapy,
  • Patients suffering from HIV/AIDS.

 

The high accuracy of our IG counting method provides a valuable tool for physicians for concluding diagnoses or requesting further patient investigation. On conventional haematology analysers, the presence of immature granulocytes is usually flagged and requires a microscopic review. Our automatic IG counting reduces this review rate significantly. Moreover, results including the presence and concentration of IGs become available within minutes – and are included in the complete CBC+DIFF analysis, making it a valuable sixth subpopulation of the white blood cells.

Benefits

Sysmex devices are especially powerful as we provide an actual IG count [# and %] and not just a ‘flag’ for immature granulocytes. Automated IG counts generally mean you can reduce the number of blood smears and the workload by manual counting.

Using IG count

The IG count alone does not let you predict sepsis or infection. However, it can support diagnosis and prediction together with other parameters such as cytokines, interleukins and CRP. It is more useful as a monitoring parameter when the patient has already been diagnosed correctly and is under treatment.

For blood samples of unknown patients with an increased IG count, blood smear preparation is still recommended. In known patients, an automated IG count can avoid the manual review while therapy monitoring infections or inflammation.

The IG count of paediatric patients, especially premature neonates or neonates younger than seven days, has to be taken with care due to their immature immune systems and the greater number of immature cells in the circulating blood.
