Lab values

You really need to check with your instructors. Specific values can vary slightly based on the book, the hospital, etc. It would do no good to memorize a set of values that are slightly off from the ones you'll be tested on. I found this extremely frustrating in school. Good luck!

nope.. too bad no more instructors for me..been out of school for a decade lol.. different hospital might have different set of values.. I'm studying for NCLEX.

Google

Amazing, right? :)

NCLEX questions will mostly either give you normal labs or wildly abnormal ones, to make up for the fact that there is some flexibility in norms in different parts of the country or institutions.

So your best bet it to understand more and memorize less. The best book for that, for anyone, is Laboratory and Diagnostic Tests with Nursing Implications by Joyce LeFever Kee. I promise you'll love it.

Thanks for that I'll try to check it out😊

Other posters are right to say that the values will be a little different everywhere you go. However, to expect you to learn something from nothing is unreasonable. Keep In mind all charts are flexible, but if you see a WBC count of 30, you will know enough to know something is wrong. This is where a little critical thinking can come in.

Here is one little chart... Men on left, women on right
