I need help with a lab question

Published

I am a lvn student and I have a question about labs that I can not find an answer to and when I asked my instructor she couldn't be bothered with it. My question is this, I know h&h stand for hemoglobin and hematocrit and they are run as two seperate labs but alway run together, I always see the values as hgn then the value, and the same with hct, yet people will say the pts h&h was #, are they combing the values to get an overall h&h value? I don't see on any lab reports h&h___ they are always printed as two seperate values. I don't want to look stupid by saying the hemoglobin was ___ and the hematocrit is____ when they can be stated as h&h was ________. I asked a friend who is a nurse and she said she had never heard of anyone saying it as h&h_____ that it is always two seperate values. So if anyone can help me with this I will be grateful.

I agree with your friend. There is no single number for H&H, it's always two numbers. Although, I think the term H&H may be used in regard to the hemoglobin, as that is usually the more important value when deciding if a patient needs blood products. So you might hear someone say that the H&H is 7.5 when they really mean the hemoglobin is 7.5. You might also hear "The H&H is 12.7 and 45." Or just 12.7, 45. If they say the two values together it can seem like one number, even though they are really saying both.

Don't over think it. :nurse: Just say the hemoglobin is ___ and the hematocrit is _____. No one will think you sound stupid.

They are two different values and are not combined. They are a measurement of two different things. The hemoglobin is X and the Hematocrit is Y.

I think you first need to understand what these lab values mean. Do you know what they measure and how they are calculated? I think if you did it'd make more sense.

The hemoglobin is measured in g/dL and the hematocrit is a % so therefore, you cannot just add them together.

Thank you all for taking the time to read and answer my question, I value your time and experience. You have cleared it up a bit for me, I can see what you mean Ashley about the hemoglobin being the most important and the staff referring to it as h&h__.

one more concept to take away about h&h is this: think about how oxygen gets delivered to the cells. you have to have a decent hematocrit (the % of your blood that is red cells) and a decent hemoglobin. if you think about it, the amount of oxygen carried in blood with a hematocrit of 30 is double the amount of blood carried by blood with a hematocrit of 15, even if they both have oxygen saturations (that's the percentage of hemoglobin that is carrying oxygen at a given time) that are the same. lots of people see, "sat of 90%, that's fine" but if the person has a low crit or hemoglobin, maybe it's not really enough oxygen in there.

neat, huh?

I don't know if I would think Hgb is the "most" important. They really go hand in hand. Each is a puzzle piece of the lab value picure. Lame metaphor. Good luck. :)
