Basic Metabolic Panel (BMP) / Chem 7 Results Explained


welcome to another MedCram lecture
this is the beginning of a series where we’re going to talk about the chem-7 as
it’s known or the basic metabolic panel and this is the structure that the chem
7 or basic metabolic panel is usually delivered in and this first column here
are the positive charges and we’ll talk about that that’s sodium and potassium
those are the abbreviations the middle column here are the negative charges
chloride and bicarbonate this is otherwise known as co2 you’ll see that
written a number of times so bicarbonate is actually measured as co2 and so
you’ll see this expressed as carbon dioxide but it’s really measuring the
bicarbonate concentration this third column has to do with the kidney and we
have the B UN never call it the bun call it the B um and then here on the bottom
we have the Kratt Neen and then here finally at the very end we have glucose
now the units that these things are reported in this first column is
milliequivalents per liter or another way of saying it is millimoles per liter
and that goes for all of these here on the left-hand column
same with this middle column this is also milliequivalents per liter or
millimoles per liter the B went in the Kratt mean however are expressed in
milligrams per deciliter and glucose also in milligrams per deciliter now
outside of the United States sometimes these are expressed differently as well
depending on the units and so we’ll be sticking to milligrams per deciliter and
so I want you to notice that the first column are positive charges the second
column are negative charges the third column here has to do with the kidney
and again this is the glucose and so that’s the basic pattern that we’re
going to be using now in this series we’re going to be going into detail in
each one of these seven values the sodium is a very important marker in the
body it’s also very important ion it is important in terms of water
and fluids and compartment and spaces
potassium is very important in terms of electrical conduction in neurons and
it’s also very important in cardiac conduction as well as other things
chloride is the counter ion for sodium and we’ll see that it it depends a lot
on the sodium concentration we’ll also see of course with bicarbonate is very
important with acid-base buffering and things of that nature that has to do
with the kidneys and here we have the kidneys and we have the be UN which is
filtered in the glomerulus but also reabsorbed and we have the creatinine
which is filtered at the glomerulus but also excreted in the distal convoluted
tubule and we’ll talk more about the B UN and the cramping and then finally
we’ll also talk about the glucose concentration and what that has to do
with now all of these items are very strictly regulated in the body and so
we’re going to be talking about when these things are low and when these
things are high and what are the systems that regulate them to keep them in the
normal range so join us as we talk about sodium first and we’ll go on to the rest
of these items thanks for joining us
