Possible for labs to measure ldh units differently? child inexplicably ill for months w/normal cbc. ldh in the 600-700s. dr: "not significantly high."

Please review: Please review this article on LDL, take a printed copy to your Dr and ask him or her to clarify... http://www.nlm.nih.gov/medlineplus/ency/article/003471.htm

Non-specific marker: The LDH test is a non specific marker of inflammation in the body.The enzyme originates from several defined sites, including liver, blood, lungs, kidneys, muscle, etc and a further test could define which area is involved. If your kid has had a vague flu like illness with muscle pains, this may be within the expected findings of the doc. A followup test should show recovery
