Lab Values for Nursing School [how to understand lab panels] + FREE QUIZ

Okay guys in this lesson we’re going to take a look at the different types of lab panels that you may run across when you’re taking care of your patients.

The beauty of these types of tests are that they can provide information quickly and they usually include more than one system. So you can take a look at your patient’s electrolytes and liver function at the same time without submitting two different types of tests. Another beautiful part of it is that they’re often performed on site, meaning that the hospital lab can perform these tests usually without a problem. That means that you get your information back quickly. It gives information about the different systems and all of the values can help point to what’s going on with your patient. These tests can be simple or they can be really complex. One thing that you want to keep in mind is if you have a patient that’s becoming sick pretty rapidly, you’re going to want to get labs that are going to give you the most information quickly.

Let’s start off by taking a look at the two most common types of metabolic panel. The first one is called the basic metabolic panel, or BMP. There are some similarities between the two panels that we’re looking at, but the thing that you want to look at when you’re looking at BMP is that it gives you a snapshot at kidney function, blood sugar, and electrolytes. The BUN and creatinine are going to give you an idea of what’s going on with the kidneys and how well they’re functioning. The glucose is going to give you an idea of sugar levels, and all of these electrolytes here give you an idea as to what your patients electrolyte status is. Again we go into all the little nuances of each lab value and other lessons so go check those out.

Like your BMP, your comprehensive metabolic panel or CMP, is going to give you your kidney values, your blood sugar levels, and your electrolyte levels. But it also gives you a lot more information. Here you can see that it gives you an idea of what’s going on with your liver with your Alk Phos, ALT, and AST. It also gives you some insight as to what’s going on with your patient’s protein levels. Don’t forget that the CMP is probably going to take longer to get back, so if you need some quick response as to what your patients electrolytes and kidneys are doing, then I would send out for a BMP vs. CMP.

The big thing that you need to understand between these two panels is that one is very basic and it gives you some real simplistic results, whereas another one is extremely complex, but if you need those values you can get them through these panels.

Another common type of lab test that you’re going to see is going to be the complete blood count or CBC. This is a really interesting test, and it’s a really common one. What it does is it gives you an idea about what’s going on with your patient’s cells. With your patients red blood cell count, or RBC, it can give you an idea as to if they have different types of anemia, along with your hemoglobin and hematocrit. Another thing that your CBC will do is it’ll give you some information about your patients immune system, through the white blood cells. It can tell you if there’s inflammatory response is happening, if there’s an infection going on, or even some possibilities of disease processes like leukemia. One really important thing that you’re going to have to think about when you’re doing a CBC is if they need a differential. A differential is a specific type of test that looks at all the different types of white blood cells. All of these white blood cells have specific roles, and sometimes you have to know exactly how many there are. Again like other values that we’re talking about in this lesson go check out the specific lessons regarding each one of these values so that you can get a better understanding of what all of these mean so that when you see them in your patient CBC you understand.

So let’s recap.
