Question : I was informed that my latest blood test shows potassium level of 5.9
My G.P. told me to have another blood test in one month.
I feel OK but wonder if I should ask for immediate attention.
I am 79 years of age.

Brief Answer:
This is not a dangerous level.

Detailed Answer:
Hi,
Thank you for using Heathcare Magic. This is not a dangerously high potassium. It is marginally above the upper limit of the normal range. Therefore, it is safe to wait one month and repeat the test. Ensure you keep well hydrated in the meantime. You do not need to do anything else.
I hope this has reassured you. If you have any further questions, please do not hesitate to contact me.
Regards,
Dr K A Pottinger,
MBChB. FRCA.
