What do low gran and high lymph mean in a blood test?

Low granulocyte (gran) levels in a blood test may indicate a weakened immune system, potentially due to infections, bone marrow disorders, or the effects of certain medications. High lymphocyte (lymph) levels often suggest an active immune response, commonly seen in viral infections, chronic inflammatory conditions, or lymphoproliferative disorders. Together, these findings can provide insights into underlying health issues and may require further investigation by a healthcare professional.
