![]() Activated partial thromboplastin time (PTT).Coagulation LevelĬoagulation levels refer to several labs, including: Partial pressure of carbon dioxide (PaCO2): 35-45 mmHgĪ medical provider may order an ABG for a variety of reasons, including but not limited to, lung failure, sepsis, pneumonia, hypovolemic shock, trauma, asthma, drug overdose, heart failure, and emphysema.Partial pressure of oxygen (PaO2): 75 to 100 mmHg.According to the National Institute of Health, typical normal values are: The aforementioned components all have different normal values and represent different aspects of blood gas. Hemoglobin: Measures the amount of hemoglobin in your blood.Oxygen content (O2CT): Measures the amount of oxygen in your blood.Oxygen saturation (O2 Sat): Measures how much hemoglobin in your blood is carrying oxygen.Bicarbonate (HCO3): Calculated using the measured values of pH and PaCO2 to determine the amount of the basic compound made from carbon dioxide (CO2).Partial pressure of carbon dioxide (PaCO2): Measures the amount of carbon dioxide in your blood and how well carbon dioxide can move out of your body.Partial pressure of oxygen (PaO2): Measures the pressure of oxygen dissolved in your blood.pH: Measures the balance of acids and bases in your blood.The test is used to check the function of the patient’s lungs and how well they are able to move oxygen into the blood and remove carbon dioxide. This lab can be used to check for medical conditions such as diabetes, high blood pressure, and kidney disease.Īn arterial blood gases (ABG) test is a blood test that measures the acidity, or pH, and the levels of oxygen (O2) and carbon dioxide (CO2) from an artery. This is a very common blood test that is run for a variety of reasons, but generally - most hospitalized patients will have this test ordered. There are two panels that are commonly referred to as a metabolic panels:Ī CMP measures all of the above and the following: According to the National Library of Medicine, a metabolic panel is a group of blood tests that provides information about your body's metabolism. NCLEX lab values questions will also assess your knowledge of metabolic panel ranges. When to Order a CBCĪ healthcare provider may order a CBC if a patient has: Hematocrit: Proportion of red blood cells to the fluid component, or plasma, in bloodĪ CBC can be used to identify infections, anemia, autoimmune disorders, bone marrow disorders, thrombocytopenia, erythrocytosis, and different types of cancer, including leukemia.Hemoglobin: Oxygen-carrying protein in red blood cells.White Blood Cell: Cells that fight infection.Red Blood Cell: Cells that carry oxygen.Complete Blood CountĪ complete blood count (CBC) measures five key components, including: Here are the common normal lab values for the NCLEX you should know. It’s important to understand the normal range for the lab values and the reason why a medical provider would order them.
