Every blood test I have for CLL requests LDH. This can monitor progress of a disease, like our CLL or tissue damage from infection etc. No doubt your blood tests include U&E, Kidney and Liver function.
Don’t panic, it is good that the consultant is being thorough.
Hopefully, someone has had the same experience and will give reassurance.
Lactate Dehydrogenase (abbreviated LD or LDH on your blood biochemicals blood test panel) is an independent measure of the growth of your CLL and can indicate Richter's Transformation/Syndrome (RT or RS), the 'high grade cancer' your consultant mentioned. While this is scary, if LDH is raised due to RT (doesn't always happen), then it is likely several times normal. The most common cause of a raised LDH in my experience and from what I've read online, is poor technique in taking your blood sample or in the transport and processing of your blood sample caused by broken blood cells. That's because there's more LDH inside cells than in your blood plasma. When blood cells get broken, they release their LDH into the plasma and you get an artificially raised LDH.
If, during your last blood test, you remember the phlebotomist struggling to get a blood sample, for example moving the needle back and forth in the vein to get an improved flow, or if your arm is more sore than usual or you've got bruising around the needle site, you can probably relax. Likewise if you feel fine. I would even contact your consultant, say that this has happened and ask if a repeated blood test is worthwhile before proceeding with the much, much more expensive PET scan. Your consultant might be hard to understand, but she is being thorough.
So... Its not a higher grade, consultants meeting next week and then treatment to begin the week after, I will no more next week but overnight stays for the first month, with target therapy intravenous drip...and then tablets for a year, does this sound familiar with anyone else's treatment... After 3 years on W&W..... I'm ready 💪
