The hematocrit blood test determines the percentage of red blood cells (RBC's) in the blood. Blood is composed mainly of red blood cells and white blood cells suspended in an almost clear fluid called serum. The hematocrit test indicates the percentage of blood by volume that is composed of red blood cells. The condition called anemia results from having too few red blood cells. Anemia causes a variety of symptoms. The hematocrit is a basic test that can tell a physician a lot about a person's health.
Preheat the oven to 400 degrees F (204 degrees C). Place the short ribs on a baking sheet, season with salt and pepper, and roast in the oven for 15 minutes. Remove the ribs from the oven, and then reduce oven temperature to 300 degrees F (149 degrees C).
Place the ribs in a roasting pan and then in the oven. Bake the ribs until tender, or about 2 hours for baby back ribs or 3 hours for spare ribs. Take the ribs out of the oven and let them cool to room temperature. Unwrap the ribs in the dish to collect the juices and transfer them to a bowl or container to reserve.
