A blood test is a routine medical screening typically done in laboratories to monitor health values and help diagnose diseases. Your blood offers many clues about your heart health. The kidneys remove waste material, fluids, and other substances from the blood.

 Although it isn't always possible at the time of your initial exam, a urine test can help your doctor diagnose conditions related to strokes including blood clots, kidney disease, diabetes, and other metabolic diseases.  These two tests are used to detect biomarkers in different bodily fluids. While these tests aren’t comparable, they are better together in efforts to diagnose irregularities and help make diagnoses.
