Help me figure this out. Elevated Serum lactate dehydrogenase level

[Wobblyheart]

I've been unwell with vague symptoms for about 20 months now.

Many tests were done but we are still not nearer the answer. I had a wide panel of bloods done and two things that stood out for me:

Serum lactate dehydrogenase level 239 u/L [125.0 - 220.0]; Above high reference limit

• it was also elevated in a similar value about a 16 months ago

Serum inorganic phosphate level 0.79 mmol/L [0.8 - 1.5]; Below low reference limit

I think LDH is key to finding out what's wrong with me. I am so scared about what would it be and so tired of not having answers.

My thoughts currently are heart disease of some sort, bowel cancer or another cancer.

Bump 😞

Your best bet is to ask the person who requested it - they must have had some sort of thought about what they were looking to diagnose/exclude when they ordered it. On its own it’s not terribly helpful - it needs to be interpreted in the context of medical history, examination, medications, other test results.

It was ordered by my GP but by a suggestion of a rapid cancer diagnostic service. They didn't want to see me in person as prevoous tests were all normal and asked to do these.

I do have extreme fatigue, night sweats and breathlessness, some bowel symptoms .

Full blood count and many other tests are still normal. But LD was about the same over a year ago when I started to feel as I am still feeling.

I just can't take the wait for answers anymore. I am collapsing with the stress of it.
