Hi folks, I have just been found to be positive for IGM Cardiolipin, but not for the other cardiolipin antibody, and I'm due to be re-tested in few weeks' time. I have also been identified as being vitamin D deficient. My last blood test showed by calcium levels to be within range, so I am now due to start on cholecalciferol (D3). My question is whether starting vitamin D prior to being re-tested for the antibodies will skew the results. Am I okay to start straight away or should I hang fire just yet? I would really welcome your thoughts - thanks.
