Re: Question about Saline Infusion Test

February 17, 2012

High alk phos is high level of bone and liver combined. Mine is normal but my

bone specific alkaline phos is high showing that it is an abnormality of bone

and not liver. I read an article that PA can cause secondary

hyperparathyroidism. This is a test for that diagnosis. Calcium is leaching

out of my bones. I am also getting decreases in calcium. A year ago it was 9.7

now 8.8 in the blood. Not sure what that means.

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.

thoughts so I can be prepared should the results be indeterminate.
