Need Help With IGF Lab Results

[USMCSS]

So I had my endo do a test on my IGF levels and the results are in. I see the one result but not sure what the .7 result means when and what Z Score is exactly even after googling it. Cam anybody break that down dumb dumb style for? See attached pic.

The labs seem to be providing standard deviation values for IGF tests more and more.

If I am correct and this is what this is, then the standard deviation of 0.7 would mean you are in the slightly high normal range for 95% of the population (sort of just to the right of the peak in a standard bell curve, if you know what I mean).

The confusing part is it says the reference range is -2.0 - +2.0. Correct me if I'm wrong but that's like saying whatever is below 2.0 is low and whatever is about 2.0 is high. Well, 0.7 is less than 2.0 correct? Also, why is there now in between low or high?

No. Picture a number line that goes from -2 to 2.

<----- -2 ----- -1 ----- 0 ----- 1 ----- 2 ----->
_________________________^
_________________________0.7 approx

0 is exactly in the middle, and a positive number, like 0.7, is on the slightly higher side of what you would expect to get in 95% of the population your age (so it will be excluding extreme outliers: people who have very high or very low results). So it is not a low result. 95% of the population will fall between the -2 and the 2, and at 0.7 you are on the slightly higher side of the middle of the 95%. This is hard to explain, so I hope you see what I mean.

I'm going to post this, and check to see if the number line comes out generally right, and if not, I will try to edit it.

Explained perfectly by Angel.

Now if only I could calculate how many ticks on a slin pin for my injection without posting on the forum.

You're a bit higher than average.

I don't often LOL at posts on this forum, but this time I literally did.

I could certainly benefit by being infected with this economy-of-words bug you've got.

Couldn't have been explained any more perfect! Thanks a ton Angel! Sad part is I guess now I won't be getting HGH from my endo lol

You're v welcome. Sorry to hear no GH.

Ya and worst part is they took me off TRT too. You can see that thread I started in the TRT section if you care to chime in

Lol. My work has me in contact with nothing but idiots, the hard of hearing, and hispanics who don't speak English. I've become very good at keeping it simple.

Sounds like you're a border patrol agent. lol I recently trained a bunch of those guys and that's pretty much how they describe their job.

Yeah, I'm very sorry to hear this. I don't recall whether they checked your thyroid and cortisol and other hormones that affect testosterone. Because I noticed (along with others) that your levels weren't super-low, and while it still might just be the test levels, when the levels aren't really low, it is usually worth checking to see if there are other co-factors that might be contributing the situation.

I know it's the VA, and they might not be as keen to do that as a private doc, but if I were you, that's information I would want to have.

Are those just the customers? Or are the medics included in that too?

Nah, I'm not LE, but we do deal with the same populations around my area.

I'm in AZ so I know the feeling all too well
