Study Notes
Chronic Kidney Disease Detection
- Glomerular filtration rate (GFR) is a laboratory value used to detect chronic kidney disease.
Bilirubin Function
- Liver function is indicated by bilirubin level.
Hypoglycemia
- Hypoglycemia is consistent with a plasma glucose level of 50 mg/dL.
-
Hypoglycemia can be caused by various conditions, including:
- Insulin overdose
- Starvation
- Alcoholism
Coagulation Tests
- Prothrombin time (PT) measures the amount of a plasma protein present in the blood.
- Mean corpuscular volume (MCV) indicates red blood cell size.
- International Normalized Ratio (INR) is commonly used to monitor the effectiveness of warfarin therapy.
- Activated partial thromboplastin time (aPTT) of 50 seconds indicates a prolonged clotting time, suggesting a potential bleeding risk.
Sensitivity Studies
- Sensitivity studies help determine the effectiveness of different antibiotics in treating diseases.
Stool Tests
- Ova and parasite (O&P) test is performed to identify a tapeworm infestation.
- Bacteria in the urine can make it appear cloudy or have an unpleasant odor.
Cardiac Muscle Damage
- Elevated levels of cardiac markers, such as troponin I and troponin T, support a suspicion of cardiac muscle damage after an infarction.
Diabetes Mellitus
- High blood glucose levels, either fasting or after a meal, are consistent with diabetes mellitus.
Obesity
- High levels of triglycerides, low levels of HDL cholesterol, and high levels of LDL cholesterol are consistent with obesity.
Blood Tests and Associated Disorders
- Complete blood count (CBC) analyzes red blood cells, white blood cells, and platelets for abnormalities, including anemia, infection, and bleeding disorders.
- Lipid panel evaluates cholesterol and triglyceride levels, indicating risk of heart disease.
- Thyroid-stimulating hormone (TSH) assesses thyroid function, diagnosing hypothyroidism or hyperthyroidism.
- Creatinine kinase (CK) measures muscle damage, particularly in the heart, brain, and skeletal muscles.
Heparin Therapy Monitoring
- Activated partial thromboplastin time (aPTT) is used to monitor heparin therapy.
Anemia
- Low levels of hemoglobin are consistent with anemia.
Warfarin Therapy
- International Normalized Ratio (INR) results are desirable for a patient on warfarin therapy, ensuring adequate anticoagulation without excessive bleeding.
Fecal Fat Stool Test
- Steatorrhea, a condition characterized by excessive fat in the stool, can be diagnosed by a fecal fat stool test.
Reasons for Culture Prescription
- Cultures are prescribed to identify the specific organism causing an infection and determine the appropriate antibiotic treatment.
Fine-Needle Aspiration Advantage
- Fine-needle aspiration is a minimally invasive procedure with high accuracy.
