You can still have elevated NK cells and have normal APS results. I have slightly elevated NK cells but normal APS levels. Unless you do an NK cell assayand other immune testing, it's impossible to know whether you have any immune issue I will say that Lovenox is part of most immune protocols because elevated NK cells can clauses use clotting. Love of may or may not be enough to treat an immune issue, but it may not be. My suggestion would be to go ahead and do a basic imunne protocol that consists of intralipids which are inexpensive, Lovenox and prednisone or dexamethasone. This will not require you to do anymore testing. If that doesn't work, then II would definitely suggest further testing as you may need something other than intralipids such as IVIG or Neupogen. Good luck.
