LDH level of 896 in child aged 2 years..what could this mean

[bazjo]

this has been going on for 18 months.. LDH is the only blood test he has had thats been abnormal... & now its at the highest ever..  896 .
his symptoms are reoccuring episodes of malaise & lethargy...sits around many days unable to really do much normal toddler activty saying he's tired & his legs hurt a bit... His lymph nodes in his neck (cervical) & nodes at base of his head enlarge & then decrease all the time (but are ALWAYS prominent even on a good period). We are desperate for any advice

[bazjo]

yes as far as i know they have & they were normal... he seems to be confusing the medical world.. no one seems to knowwhats wrong with him.........
the only other recent test results that were abnormal were:
His CH 100 total Compliment level was very raised at 1200 (normal I think was 200)- but compents C3 & C4 were normal??
His IGE is massivly raised at 600 (normal should be under 32)
His Albumin levels are slighty raised too.

any ideas's?? Also.. at the moment he seems quite well.. then he will go down hill again... this thing seems to be in episodes?? with short well periods in between the episodes?
