Maybe possible to use a thinner gauge needle. Eg 32g thinner than 30g 28g etc that should help a bit if can get enough of droplet to check. You could if not tried already reduce depth of lancet. Maybe hand moisturiser could help a little too. Guessing you clean with warm water. Ensure to rotate fingers as much as possible using both the left and right sides of each finger if not doing already. Combination of above hopefully will help.
