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).
Slow Roasting the Ribs. Another way to precook ribs for the grill is in your oven or slow cooker. Season the ribs ahead of time with a dry rub made from herbs and spices or dried spicy dip mix, then place them on a sheet pan or in your slow cooker. Use the low setting on the slow cooker, or preheat your oven to 250 degrees Fahrenheit. Slow-roast the ribs until they are nearly fork-tender, usually for 2 1/2 to 4 hours depending on the size of the rack. Transfer the ribs to your grill, and finish them over direct heat with your favorite sauce.
