Hemoglobin, that is in the teens, 14-18...Glo means young, like the teenful glow = hemoglobin
Hemotocrit (spelling), means old, so it is 35-40

Unfortunately, I don't have any tricks for that. I guess I just learned them the old-fashioned way. It won't help you on tests if you're a student, but you might consider investing in one of those pocket guides for nurses that are available at medical bookstores. Some people even make their own, with laminated index cards, a hole punch, and a ring.

Learn one a day. That is how I did it. It makes it really easy.

Flashcards, flashcards, flashcards is how I remembered them. I used to keep them in my purse and when I had downtime, waiting in lines etc, I would pull them out and go through them.

I made up stupid statements that helped me remember them. Our school uses their own values which we had to know. So I would remember - I ate 3, 5 1/2 inch bananas - for potassium 3 - 5.5. The pool was 100 feet long, give or take 5 - cl; 95-105. Buns 5 for a quarter, BUN 5 - 25. And so on, I shared with a friend and she said they really helped her remember them also - so try making up some sentences relating to things you know to help remember them.

PTT 60-70 or 1 ½ times higher if on Heparin
PT 11.0 - 12.5 or 2.o -3.5 times higher if on coumadin
INR 2.0-3.5 for coumadin
WBC 5-10
RBC 5
HCT 40

On vacation I -

Interesting! I'll have to try some of these tips.

Different texts have different #'s. Whatever is the standard for your school, make a table or a copy of teh values on a sheet of paper and leave it in your car. At every red stop light, look over 2-3 values until they're stuck in your head.
It worked for me.

Here are a few that helped me:
Na = # of grains of salt on a pretzel = 135-145
K = # of bananas that usually turn brown on the counter = 3.5-5
Cl = temperature when you really want to go swimming = 95-105
Ca = age when kids break bones = 9-10.5
I know some of these are a stretch, but I've never forgotten them.

well, for electrolytes, I put them in alphabetical order...
Calcium: 8.5-10.5
Chloride: 96-106
-----start new sequence of lowest to highest---
Magnesium: 1.5-2.5
Phosphorus: 2.5-4.5
Potassium: 3.5-5.5
Sodium: 135-145
it's sorta weird, but i like putting things in order.

I don't have my lab results book handy but I'm fairly sure that there is a mistake in studentnursemommyof3's post with the mnemonic device. The norm for Ca+ is around 9.5-10.5 so the mnemonic should be "Ate 4 bananas with 10 glasses of milk, read 2 magazines about 2 fossils..." It is a good tool though, I used it when I was relearning labs for the NCLEX. While it doesn't give ranges at least it helps you remember the mean.
