Frequently asked questions

What does a high neutrophil count mean?
A high neutrophil count often means your body is fighting an infection or inflammation. It could also be due to stress, certain medications, or underlying conditions like chronic inflammation or cancer.
What does a low neutrophil count mean?
A low neutrophil count may indicate a weakened immune response, which can make you more susceptible to infections. This could be due to autoimmune diseases, certain medications, or blood disorders like leukemia.
Can diet affect neutrophil counts?
Diet can influence overall blood health, but it doesn’t directly affect neutrophil counts. Eating a balanced diet rich in vitamins and minerals may support immune function, though results depend on the test and your health status.
