Also there is continuous weight gain since 1 years (approx 10 kg, current weight 58.5 kg). I have following question regarding this: 1) Why reference values are different in second case, as all tests are done at Lal pathlabs? 2) Can these high values lead to weight gain and swelling in body? 3) How to get these values down to average from higher side?
