Thigh pain
When doctors prescribe medications that affect the CBC, they periodically test the patient's blood. thigh pain Thigh pain. Creatinine--This blood test is commonly ordered in patients who have a rheumatic disease, such as lupus, to monitor for underlying kidney disease. Creatinine is a breakdown product of creatine, which is an important component of muscle. It is excreted from the body entirely by the kidneys, and the level remains constant and normal when kidney function is normal. thigh pain Shoulder-pain. Erythrocyte sedimentation rate (sed rate)--This blood test is used to detect inflammation in the body. Higher sed rates indicate the presence of inflammation and are typical of many forms of arthritis, such as rheumatoid arthritis and ankylosing spondylitis, and many of the connective tissue diseases. Hematocrit (PCV, packed cell volume)--This test and the test for hemoglobin (a substance in the red blood cells that carries oxygen throughout the body) measure the number of red blood cells present in a sample of blood. thigh pain Pain-under-left-rib. A decrease in the number of red blood cells (anemia) is common in people who have inflammatory arthritis or another rheumatic disease. Rheumatoid factor--This test detects the presence of rheumatoid factor, an antibody found in the blood of most (but not all) people who have rheumatoid arthritis. Rheumatoid factor may be found in many diseases besides rheumatoid arthritis, and sometimes in people without health problems. Synovial fluid examination--Synovial fluid may be examined for white blood cells (found in patients with rheumatoid arthritis and infections), bacteria or viruses (found in patients with infectious arthritis), or crystals in the joint (found in patients with gout or other types of crystal-induced arthritis). To obtain a specimen, the doctor injects a local anesthetic, then inserts a needle into the joint to withdraw the synovial fluid into a syringe. The procedure is called arthrocentesis or joint aspiration. Urinalysis--In this test, a urine sample is studied for protein, red blood cells, white blood cells, and bacteria. These abnormalities may indicate kidney disease, which may be seen in several rheumatic diseases, including lupus. Some medications used to treat arthritis can also cause abnormal findings on urinalysis.
