Question about Saline Infusion Test

February 17, 2012

I went ahead and had the saline infusion test done but wondered if Dr. Grim

could answer a question about it for me. I know you do not do it anymore, but I

thought that since I do not intake much salt it would ensure I got enough to

make the test more reliable. However, after taking 4 weeks to get the test done

and today the infusion center had never done one. I brought up the protocol I

got online for it and this helped them know what tubes to use for the lab draw

and the positioning issues.

I slept for the first 2 hours then had to go to the bathroom. I did convince

them to let me check my total urine eliminated. I saw that the iv had it at a

rate of 250ml/hr at that time. I questioned the nurse and she looked back and

said oh i thought it was only 1 liter not 2. 2 hours already into the test and

i have only gotten in 500ml. She then raised the rate to 810ml/hr and was able

to get the 2 liters in 2 hours.

My question, 1. will that mess up effect the lab results and 2. will it effect

the urine excretion amount since it was so slow at first, then really fast for

the last 2 hours. My urine was 1.1L in the 4 hours of testing.

It will take a week for the labs, but I just wanted to know your thoughts so I

can be prepared should the results be indeterminate.
