The Importance Of Blood Test Experiments

Better Essays

Blood test measurements were gathering data on the following variables: LDL-P concentrations and particle analysis, LDL-C concentrations, HDL concentrations, lipoprotein levels, and triglyceride levels. Other variables the researchers were interested in were 125I-LDL concentrations in urine, degree of stenosis in extracranial and intracranial arteries, stroke severity, functional outcome 3 months post stroke, CVD and related stroke events, and LDL receptor types. The variables that the researchers controlled for in these particular studies were the types of patients used, such as excluding patients due to not agreeing to have a blood sample taken, those with prior risk for cardiac sourced embolism, and specific diets for the patients …show more content…

The two most common methods to gathering data utilized by the researchers in the various FH studies either employed direct data collection, such as from medical records from their visits with physicians or while they are inpatient in a hospital, or the researchers would change some aspect of the person’s life and then collect pertinent data over a set time period. The independent variables that these studies focused on included hypertensive meds, antidiabetic meds, lipid-lowering meds, statins, intestinal cholesterol absorption inhibitors, prescription omega 3 fatty acids, and antiplatelet agents that the patients were put on by their physicians, along with an isocaloric diet created specifically for that particular study, the IV injected solution for the lipoprotein turnover studies, and the lard-based diet. The dependent variables that have been studied thus far include the degree of stenosis, stroke severity, functional outcome, LDL particle size, the lipid profile variables including total cholesterol, LDL, and HDL measurement, catabolic rate of LDL, plasma triglyceride concentrations, LDL receptor activity, and sterol excretion.
