The half-life of a neutrophil is less than one-half of a day. [1]

Diagnosis

Grading

Grading is:[2]

  • Grade 1: < 2.0 x 109/L (< 2000/mm3) and > 1.1 x 109/L (> 1500/mm3)
  • Grade 2: < 1.5 x 109/L (< 1500/mm3) and > 1.0 x 109/L (> 1000/mm3)
  • Grade 3: < 1.0 x 109/L (< 1000/mm3) and > 0.5 x 109/L (> 500/mm3)
  • Grade 4: < 0.5 x 109/L (< 500/mm3)

Febrile neutropenia

Clinical practice guidelines define febrile neutropenia as "a single oral temperature of >=38.3°C (101°F) or a temperature of >=38.0°C (100.4°F) for >= 1 h. Neutropenia is defined as a neutrophil count of <500 cells/mm3, or a count of <1000 cells/mm3 with a predicted decrease to <500 cells/mm3"[3]

A clinical prediction rule can estimate the risk of morbidity in the febrile patient with neutropenia.[4] A score of >=21 indicates low risk.

Prevention

Granulocyte colony-stimulating factor is indicated in selected settings.[5][6]
