Question about blood work

As a trans male, do you need to adjust your dosage if your levels are within 2.2 - 10.5 ng/mL? Just got my results back and it's 6.77ng/mL. I'm on 50-75 mg test c weekly (I use the airlocking method so the dosage is a bit hard to know accurately). I'd rather not have to use more but yeah...lmk
