The HCT, which stands for hematocrit, blood test measures the amount of red blood cells in a blood sample. This test is also referred to as a crit or a PCV, which means packed cell volume. The HCT blood test is usually done as part of a CBC, or complete blood count, blood test.
Osteoarthritis is a progressive form of arthritis characterized by breakdown of the cartilage in joints. Osteoarthritis (OA), also known as degenerative joint disease and wear and tear arthritis, causes pain in the joints with activity. The knees and the hips are common locations for osteoarthritis. Osteoarthritis is common in people over 60 years of age, but it can affect younger people, particularly where they have had joint injury or joint surgery.
Also called wear-and-tear arthritis or degenerative joint disease, osteoarthritis is characterized by progressive wearing away of the cartilage in the joint. As the protective cartilage is worn away, bone is exposed, the knee becomes swollen, and activities become increasingly painful.
