Generally you don't have to worry. Your doctor watches those numbers for you. The ideal range is on your Complete Blood Cell Count test results page, it's the same for everyone. Immunomodulators are very, very slow working medications and as a result your WBC and other numbers change very, very slowly over a period of months. Like a change of a couple tenths between tests (like from a 4.2 to a 4.0). They can tell well in advance that the trend is heading low, make adjustments well in advance of problems.
If you're curious and have access to test results (my lab has an app where I can view them) then look at the test results and see, results indicate the ideal range for each item and whether you're in, above, or below range for each item. Platelets, RBC, or WBC are generally what they're watching, and they're measured several ways (a count, volume, and percentage) in a typical Complete Blood Cell Count test.
The numbers vary some by CBC test, but it's usually anything consistently under 3.5 for WBC that's below range and concerning and will result in a dosage change. 3.5 itself isn't dangerous (you'd have to get into the 2's for that), but it's a warning sign to change things.
While on immunomodulators they should also be monitoring your Hepatic (liver) Function Panel blood test. Essentially, they're looking for enzymes building up to a large number (also appearing, above and out of range) Immunomodulators are metabolized within the liver, high enzymes signal trouble and they'd adjust dosage or discontinue.
