Which diagnostic test involves removing fluid from a joint?
Arthrocentesis is a diagnostic test that involves removing fluid from a joint. It is typically done to analyze the fluid for signs of infection, inflammation, or other underlying conditions causing joint pain or swelling.
Culture - joint fluid?
DefinitionJoint fluid culture is a laboratory test to detect infection-causing organisms in a sample of fluid surrounding a joint.Alternative NamesJoint fluid cultureHow the test is performedA sample of joint fluid is needed. This may be done in a doctor's office using a needle, or during an operating room procedure. For more information on this procedure, see joint fluid aspiration.The fluid sample is sent to a laboratory where it is placed in a special dish and watched to see if bacteria, fungi, or viruses grow. This is called a culture.If such microorganisms are detected, other tests may be done to further identify the infection-causing substance and determine the best treatment.How to prepare for the testThere is no special preparation needed for the lab culture. For information on preparing for the removal of joint fluid, see joint fluid aspiration.How the test will feelThe joint fluid culture is done in a laboratory and does not involve the patient.For information on how the procedure to remove joint fluid feels, see joint fluid aspiration.Why the test is performedYour doctor may order this test if you have unexplained pain and inflammation of a joint or a suspected joint infection.Normal ValuesThe test result is considered normal if no organisms (bacteria, fungi, viruses) grow in the laboratory dish.Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.What abnormal results meanAbnormal results are a sign of infection in the joint. Infections may include:Bacterial arthritisFungal arthritisGonococcal arthritisTurberculous arthritisWhat the risks areThere are no risks to the patient associated with a lab culture. For risks related to the removal of joint fluid, see joint fluid aspiration.ReferencesEspinoza LR. Infections of bursae, joints, and bones. In: Goldman L, Ausiello D, eds. Cecil Medicine. 23rd ed.

Joint fluid Gram stain?
DefinitionJoint fluid Gram stain is a laboratory test to identify bacteria in a sample of joint fluid using a special series of stains (colors). The Gram stain method is one of the most commonly used methods to rapidly diagnose bacterial infections.Alternative NamesGram stain of joint fluidHow the test is performedA sample of joint fluid is needed. For information on how this procedure is done, see joint fluid aspiration.The fluid sample is sent to a lab where a small drop is placed in a very thin layer onto a microscope slide. This is called a smear. Several different colored stains are applied to the sample. The laboratory personnel will look at the stained smear under a microscope to see if bacteria are present. The color, size, and shape of the cells help identify the bacteria.How to prepare for the testFor information on how to prepare for the removal of joint fluid, see joint fluid aspiration.How the test will feelFor information on how it will feel when the joint fluid is removed, see joint fluid aspiration.Why the test is performedThe test is performed when there is unexplained swelling, joint pain, and inflammation of a joint, or to check for suspected joint infection.Normal ValuesA normal result means no bacteria are present on the gram stain.Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.What abnormal results meanAbnormal results mean bacteria were seen on the Gram stain. This may be a sign of a joint infection, for example, gonococcal arthritis or arthritis due to Staphylococcus aureus.What the risks areThere is no risk to the patient associated with a Gram stain.

What diagnostic test removes cerebrospinal fluid with a needle?
A lumbar puncture, also known as a spinal tap, is a diagnostic test that removes cerebrospinal fluid from the spinal canal using a needle inserted between the lumbar vertebrae. This procedure can help diagnose various neurological conditions such as infections, bleeding, and inflammatory diseases affecting the brain and spinal cord.
What is a saline meniscus test?
A saline meniscus test is a diagnostic procedure used to assess the integrity of the meniscus in the knee joint. It involves injecting saline solution into the knee joint to create a meniscus-like bulge. By evaluating the stability and response of this saline meniscus, healthcare providers can gather information about the condition of the knee's meniscus.

Which diagnostic test is used to determine cause of pain or swelling in joint?
arthocentesis
How is a sweep test done?
A sweep test is performed to assess the presence of fluid in a joint, typically the knee. The examiner uses their hand to push fluid from the joint space toward the midline of the knee while simultaneously observing for any bulging or swelling on the opposite side. If fluid is present, a wave of fluid can be seen returning to the area, indicating a positive sweep test. This test helps diagnose conditions like joint effusion or inflammation.

Synovial fluid analysis?
DefinitionSynovial fluid analysis is a group of tests that examine joint (synovial) fluid. The tests help diagnose and treat joint-related problems.Alternative NamesJoint fluid analysis; Joint fluid aspirationHow the test is performedA sample of synovial fluid is needed for this test. Synovial fluid is normally a thick, straw-colored liquid found in small amounts in joints, bursae, and tendon sheaths.After the area is cleaned, the health care provider will insert a sterile needle through the skin and into the joint space. Once in the joint, fluid is drawn through the needle into a sterile syringe.The fluid sample is sent to the laboratory. The laboratory technician will check the sample's color and clarity, and then place it under a microscope to check it for red and white blood cells, crystals (in the case of gout), and bacteria. In addition, there may be a chemical analysis, and if infection is a concern, a sample will be cultured to see if any bacteria grow.How to prepare for the testNormally, no special preparation is necessary, but contact your health care provider before the test to make sure. Tell your doctor if you are taking blood thinners, as they can affect test results.How the test will feelOccasionally, the health care provider will first inject local anesthesia with a small needle, which will sting. The aspiration is done with a larger needle and may also cause some pain. The procedure usually lasts less than one minute.Why the test is performedThe test can help diagnose the cause of pain or swelling in joints. Removing the fluid can also help relieve joint pain.This test may be used to diagnose:GoutInfectionOther inflammatory joint conditionsJoint injuryOsteoarthritisWhat abnormal results meanAbnormal joint fluid may look cloudy or abnormally thick.Blood in the joint fluid may be a sign of injury inside the joint or a body-wide bleeding problem. An excess amount of normal synovial fluid can also be a sign of osteoarthritis.What the risks areInfection of the joint -- unusual but more common with repeated aspirationsBleeding into the joint spaceSpecial considerationsIce or cold packs may be applied to the joint for 24 to 36 hours after the test to reduce the swelling and joint pain. Depending on the exact problem, you can probably resume your normal activities after the procedure. Talk to your health care provider to determine what activity is most appropriate for you.ReferencesKnight JA, Kjeldsberg CR. Cerebrospinal, synovial, and serous body fluids.
