hi,
EGFR, is renal function test, as it is in borderline, it is mentioned it has to be interpreted with caution. so, renal function is compromised.
dry mouth, difficulty in swallowing,
chest pain, rashes are indicative of autoimmune disorder (
vasculitis, inflammation of glands, oseophagus, skin blood vessels etc.).
his last admission histroy of pain abdomen and rash on joints and stopping with
steroids is classical example of Henoch–Schönlein purpura, which is also autoimmune disorder.
it is not related to MND (mottor neuron disease).
may other tests for other other auto immune disease has to tested.
anti-cytoplasmic antibody is antibody against cell cytoplasm, so body identifies its own part as foreign and tries to attack causing destruction (key part in any
autoimmune disease). this is increased in one of autoimmune disease.
wishing him good health
