Hello from JustAnswer. This is Dr. Love.

These numbers are not worrisome. The percentages for each type of WBC is not as important as the actual numbers of each type of WBC. The total WBC is the sum of five different types of WBCs, and the neutrophils and the lymphocytes are the most common two types. The actual numbers for each type of WBC are obtained by multiplying the total WBC by the percentage of each type. The values that you typed in the test of your question is different than the values on the attached lab report, but the numbers are similar.

In doing the math, when using the values in the text of your question, the total WBC of 8.9 and the 23% neutrophils yields an actual count of 2.05. The 67% lymphocytes yields an actual count of 5.96

Similarly, when using the values on the attached lab report, the total WBC of 10.7 and the 25% neutrophils yields an actual count of 2.68. The 63% lymphocytes yields an actual count of 6.74.

In either case, the actual numbers are within the normal range that would be expected for a 3.5 year old. It is important to note that the normal range for the total WBC, neutrophils, and lymphocytes varies according to the age of the patient. The normal ranges on the attached lab report appear to be the general normal range, which means that it really only applies to adults. See http://a2.mayomedicallaboratories.com/webjc/attachments/96/87f7989-complete-blood-count-normal-pediatric-values.pdf. The normal range can vary somewhat by the lab method that is used, but this is a common example of normal ranges by the age of the patient.

So, none of these values are abnormal, and they certainly are not worrisome for cancer.
