Episodes

Triglycerides (TG) Lab Values

9/27/2023

Normal <150 mg/dL Indications Description Triglycerides (TG) are required to provide energy during the metabolic process, excess triglycerides are stored in adipose tissue. What would cause increased levels? What would cause decreased levels?

Duration:00:03:54

Sodium (Na+) Lab Values

9/25/2023

Normal 135-145 mEq/L Indications Description Sodium (Na+) is the most abundant cation in extracellular fluid. Sodium aids in osmotic pressure, renal retention and excretion of water, acid-base balance, regulation of other cations and anions in the body. Sodium plays a role in blood pressure regulation and stimulation of neuromuscular reactions. Sodium and water have a direct relationship; water follows salt. What would cause increased levels? What would cause decreased levels?

Duration:00:04:07

Potassium (K+) Lab Values

9/20/2023

Normal 3.5 - 5.0 mEq/L Indications Description Potassium (K+) is the most abundant intracellular cation and plays a vital role in the transmission of electrical impulses in cardiac and skeletal muscle. It plays a role in acid base equilibrium. In states of acidosis hydrogen will enter the cell which will force potassium out of the cell. A 0.1 decrease in pH will cause a 0.5 increase in K+. What would cause increased levels? What would cause decreased levels?

Duration:00:04:36

Partial Thromboplastin Time (PTT) Lab Values

9/18/2023

Normal 25 - 35 seconds Indications Description Partial Thromboplastin Time (PTT)evaluates the function of factors I, II, V, VIII, IX, X, XI, and XII. PTT represents the amount of time required for a fibrin clot to form. Monitors therapeutic ranges for people taking Heparin. What would cause increased levels? What would cause decreased levels?

Duration:00:03:17

Oxygen Saturation (SaO2) Lab Values

9/13/2023

Normal 95 - 100% Indications Description Oxygen saturation (SaO2) is a measurement of the percentage of how much hemoglobin is saturated with oxygen. Oxygen is transported in the blood in two ways: oxygen dissolved in blood plasma (pO2) and oxygen bound to hemoglobin (SaO2). About 97% of oxygen is bound to hemoglobin while 3% is dissolved in plasma. SaO2 and pO2 have direct relationships, if one is decreased so is the other. The relationship between oxygen saturation (SaO2) and partial pressure O2 (PaO2) is referred to as the oxyhemoglobin (HbO2) dissociation curve. SaO2 of about 90% is associated with PaO2 of about 60 mmHg. What would cause increased levels? What would cause decreased levels?

Duration:00:03:24

Osmolality Lab Values

9/11/2023

Normal 261 – 280 mOsm/kg Indications Description Osmolality is a measure of the particles in solution. The size, shape, and charge of the particles do not impact the osmolality What would cause increased levels? What would cause decreased levels?

Duration:00:05:17

Magnesium (Mg) Lab Values

9/6/2023

Normal 1.6 – 2.6 mg/dL Indications Description Magnesium (Mg) is a cation necessary for protein synthesis, nucleic acid synthesis, muscle contraction, ATP (adenosine triphosphate) use, nerve impulse conduction, and blood clotting. Magnesium affects the absorption of sodium, calcium, phosphorus, potassium. What would cause increased levels? What would cause decreased levels?

Duration:00:03:42

Low Density Lipoprotein (LDL) Lab Values

9/4/2023

Normal <70 mg/dL Indications Description Cholesterol is transported via lipoproteins. There are multiple types of lipoproteins and they each have slightly different functions: high-density lipoprotein (HDL), low-density lipoprotein, LDL, and very low-density lipoprotein (VLDL). LDL cholesterol is considered bad cholesterol because as it travels through the blood, it deposits cholesterol into the lining of blood vessels, causing atherosclerosis and an increase in cardiovascular disease. What would cause increased levels? What would cause decreased levels?

Duration:00:03:24

Lactic Acid Lab Values

8/30/2023

Normal 0.3 -2.6 mmol/L Indications Description Lactate (Lactic Acid) is a byproduct of anaerobic metabolism. Normally, the tissues use aerobic metabolism to breakdown glucose for energy and the byproduct is CO2 and H2O which we excrete through our kidneys and exhalation. However, if the tissues are starved of oxygen (hypoxic), they use anaerobic metabolism. This can be compounded if the liver is also hypoxic causing the liver to be unable to clear the lactic acid. What would cause increased levels? What would cause decreased levels?

Duration:00:04:00

International Normalized Ratio (INR) Lab Values

8/28/2023

Normal 0.8 - 1.2 Therapeutic Levels of Warfarin 2.0 – 3.5 Indications Description International normalized ratio(INR) takes results from a prothrombin time test and standardizes it regardless of collection method. What would cause increased levels? What would cause decreased levels?

Duration:00:04:15

High Density Lipoprotein (HDL) Lab Values

8/23/2023

Normal >60 optimal mg/dL Indications Description Cholesterol is transported via lipoproteins. There are multiple types of lipoproteins and they each have slightly different functions: high-density lipoprotein (HDL), low-density lipoprotein (LDL) very low-density lipoprotein (VLDL). HDL cholesterol is considered the good cholesterol because it travels through the blood picking up extra cholesterol and taking it back to the liver. What would cause increased levels? What would cause decreased levels?

Duration:00:03:14

Glycosylated Hemoglobin(HgbA1c) Lab Values

8/21/2023

Normal 5.6-7.5 % of total Hgb Indications Description Glycosylated Hemoglobin (HbA1c) is the combination of glucose and hemoglobin. When glucose is elevated in the blood the amount of glycosylated hemoglobin increases proportionally. A red blood cells lifespan is about 4 months, so you can get an idea of blood sugar control over the last several months. What would cause increased levels? What would cause decreased levels?

Duration:00:03:29

Folic Acid Lab Values

8/16/2023

Normal 2 - 20 ng/mL Indications Description Folic acid is an essential water soluble B vitamin. It is stored in the liver and is an important part of Red Blood Cell (RBC) and White Blood Cell (WBC) function, DNA replication, and cell division. What would cause increased levels? What would cause decreased levels?

Duration:00:03:07

Ferritin Lab Values

8/14/2023

Normal 20-300 ng/mL Indications Description Ferritin is a protein that stores iron. It is formed in the liver spleen and bone marrow. Ferritin in the blood is usually proportional to stored ferritin. Ferritin is a more sensitive and specific test for identifying iron-deficiency anemia, however, it is usually measured in conjunction with total iron binding capacity and iron. What would cause increased levels? What would cause decreased levels?

Duration:00:03:43

Chloride (Cl- ) Lab Values

8/9/2023

Normal 96-108 mEq/L Indications Description Chloride (Cl-), an anion found in the blood, works together with sodium to help maintain oncotic pressure and water balance in the body. Chloride is inversely related to bicarbonate levels in the blood. Chloride is also part of hydrochloric acid (HCL) which is utilized in the stomach to breakdown food. When red blood cells (RBCs) take up CO2 they take up chloride as well. The negative ion bicarbonate then leaves the red blood cell so that the electrical charge is maintained. Extra chloride is excreted into the urine by the kidneys. What would cause increased levels? What would cause decreased levels?

Duration:00:04:44

Calcium (Ca2+) Lab Values

8/7/2023

Normal 8.4-10.2 mg/dL Indications Description Calcium (Ca+), a positive ion in the body, is necessary for neuromuscular processes, bone mineralization, and hormonal secretion. The parathyroid gland and vitamin D are responsible for calcium regulation in the body. In the blood, about half of calcium travels in ion form, the other half is bound to proteins like albumin. When albumin levels are low, calcium levels will appear lower. Calcium has an important relationship with phosphorus: they are inversely proportional. What would cause increased levels? What would cause decreased levels?

Duration:00:06:26

Aspartate Aminotransferase (AST) Lab Values

8/2/2023

Normal 12-37 U/L Indications Description Aspartate Aminotransferase (AST) is an enzyme primarily found in liver and heart cells, and to a smaller extent, AST can also be found in the pancreas, kidneys, skeletal muscle, and brain. Levels of AST increase from cell death (necrosis) because the AST enzyme is released into the blood. What would cause increased levels? What would cause decreased levels?

Duration:00:03:27

Amylase Lab Values

7/31/2023

Normal 0-130 U/L Indications Description Amylase is made in the pancreas. It is an enzyme that breaks down carbohydrates to allow our body to absorb it. Monitoring amylase levels can help identify problems with the pancreas. What would cause increased levels? What would cause decreased levels?
