Flashcards in Chemistries Deck (46):
1

What do we look for with blood chemistries?

Waste, drugs, toxic substances, cell damage indication, non functional metabolites, substances with biological functions

2

Why do we test chemistries?

Screening, rule out or confirm disease, monitor disease, preanesthetic, monitor organ function (liver, kidney), emergency medicine

3

What tube is used for chemistries?

Green top

4

Must separate plasma within ______ hour(s)

One

5

What we Check for in liver.

Carbohydrate metabolism, plasma protein synthesis, lipid metabolism, storage

6

Two enzymes found in the cytoplasm of the liver.

ALT (alanine amino transferase), AST (aspartate amino transferase)

7

AST and ALT is associated to...

Superficial cell damage

8

Two enzymes found in deeper structures.

ALKP (alkaline phosphatase), GGT (gamma glutamyl transferase)

9

Less than 2-4 times the high end of the reference range.

Mild elevation

10

Over 2-4 times the high end of the reference range.

Severe elevation

Liver health indicators.

Albumin, glucose, clotting factors, cholesterol

12

Hypercholesterolemia

Blocked bile duct.

13

Hypocholesterolnemia

Hepatic failure

14

From breakdown of hemoglobin.

Total bilirubin

15

Hyperbilirubinemia

Gall bladder dysfunction, I'll duct destruction, liver disease that causes inability to process bile (jaundice)

16

Responsible for fat absorption

Bile acids

17

What is total protein used to access?

Hydration, nutrition, liver function (serum proteins made in the liver)

18

Forms the matrix of clots

Fibrinogen

19

What do we need our kidneys for?

Water, electrolyte, ph balance, eliminates waste, productions of hormones, stimulates red blood cell production (erythropoietin)

20

Values associated with kidneys.

Blood urea nitrogen, creatinine

21

And end product of protein metabolism exceeded by the kidneys

Urea

22

Increase BUN level.

Renal insufficiency, dehydration, strenuous exercise

23

By product of muscle metabolism.

Creat

24

Prices hormones including insulin.

Pancreas

25

Produced by liver , controlled by pancreas

Glucose (GLU)

26

Diabetes mellitus (increased glucose)

Hyperglycemia

27

Low glucose,

Hypoglycemia

28

Breaks down starches and sugars.

29

Breaks down long chain fatty acids and lipids

Lipase (LIPA)

30

What is a snap (cPL) used for?

Checks lipase (pancreatitis)

31

Gives and a 1-2 week glucose bound to albumin.

Fructosamine (FRUCT)

32

Help maintain water balance, osmotic pressure, muscle and nervous function

Electrolytes

33

First indication of dehydration.

Electrolytes

34

Most common intracellular cation

Potassium K

35

50% found in bones.

Normal ph of the body

7.4

39

What does a chemistry measure?

Proteins and chemicals

40

How long after drawing blood do we have to run a chemistry?

One hour or glucose is affected

41

What affects glucose?

Contact with red cells, stress

42

What electrolyte is most common intracellular cation?

Potassium

43

What electrolyte is most common extracelluar cation?

Sodium

44

What three things make up total protein?

Albumin, globulin, fibrinogen

45

What cause glucose uria?

Glucose gets too high and the kidneys to filter out so it dumps out and ends up in the bloodstream and therefore the urine.

46

What does globulin do?

Moves hormone around
