There are several reasons for normal blood count and swollen lymph nodes: 1. Lymph node hyperplasia, often caused by infection or lymphadenitis and other diseases, after the infection is controlled, because the lymph nodes have been hyperplastic, it is difficult to return to the original state, so there will be swollen lymph nodes, but there is not necessarily inflammation in the body, so the blood count is normal. 2. Inflammation causes swollen lymph nodes, but due to the blood count is not sensitive. The reason is that the blood test to determine the inflammation is only a reference, not an absolute value, you can also refer to the C-reactive protein test to determine whether the body really has inflammation, lymph node swelling may also be the presence of inflammation, but not from the blood reaction. 3, systemic diseases, such as connective tissue disease, cancer metastasis, etc. caused by the blood test is also normal.
