What does neutropenia mean?
a
Your hemoglobin is low
Hemoglobin measures red blood cells. Neutropenia refers only to neutrophils, a type of white blood cell.
b
You have fewer neutrophils than the lab’s usual range
Correct! Neutropenia means your neutrophil count is below the lab’s reference range.
c
Your white blood cell count is always dangerously low
Some people have normal or near-normal white counts even when neutrophils are low.
d
You have an infection that needs antibiotics
Neutropenia does not mean infection. Many people with neutropenia are completely well.
Which of the following is TRUE for most people with mild isolated neutropenia (ANC 1.0–1.5)?
a
They require antibiotics
Mild neutropenia does not require antibiotics unless an infection is present.
b
They are at increased risk for infection
Mild isolated neutropenia does not increase infection risk.
c
They usually feel well and have no restrictions
Correct! Most people with mild isolated neutropenia live completely normal lives.
d
hey need a bone marrow biopsy
Bone marrow biopsy is rarely needed for stable isolated neutropenia.
Which of the following is a common and benign cause of isolated neutropenia?
a
Severe bacterial infection
Severe infections usually cause high neutrophils, not low.
b
Leukemia
Leukemia is rare, and it almost never appears as isolated neutropenia with normal hemoglobin and platelets.
c
Chemotherapy
Chemotherapy can cause neutropenia but not isolated, benign neutropenia — and it carries different risks and management.
d
Duffy-Associated Neutrophil Count (DANC)
Correct! DANC is a normal genetic variant found in many people and does not increase infection risk.
When does neutropenia usually require more urgent evaluation?
a
When the ANC is stable around 1.2 ×10⁹/L
This is mild neutropenia and is usually safe.
b
When the total white blood cell count is slightly low
A low or normal white count can happen with neutropenia and is not by itself dangerous.
c
When the ANC is <0.5 ×10⁹/L, is falling, or when other blood counts become abnormal
Correct! Severe neutropenia or changes in other blood counts may require more detailed evaluation.
d
When you feel perfectly well
Feeling well is reassuring and usually means the neutropenia is mild and safe.
Which activity is safe for people with mild to moderate isolated neutropenia?
a
Avoiding all crowds
People with mild isolated neutropenia do not need to avoid crowds or normal activities.
b
Avoiding exercise
Exercise is safe.
c
Normal work, diet, travel, and daily life
Correct! Severe neutropenia or changes in other blood counts may require more detailed evaluation.
d
Taking preventive antibiotics
These are not recommended unless there is severe neutropenia or frequent infections.
