We have a problem with one patient who has given the following results:
Date VMA HVA Adrenaline Noradrenaline Dopamine
Volume
21-22 15 27 0.02 0.27 0.75
1.98L
22-23 21 60 0.02 0.42 1.23
2.1L
23-23 28 104 0.03 0.46 1.53
3.1L
Ref range
VMA <35 umol/24hrs
HVA < 44 umol/24hrs
Adrenaline <0.10 umol/24hrs
Noradrenaline < 0.57 umol/24hrs
Dopmaine < 2.50 umol/24hrs
Medication:
Moxonidine 200mcg twice a day
Doxazosin 4mg twice a day
Frusemide 40 mg/day
Cervistatin 300mcg a day
Zirtek and HRT.
The dopamine and HVA results do not seem compatible and we suspect drug
interference.
If you have a non HPLC assay for these please get in touch.
Any ideas welcome.
Edward Kearney.
