Osteoarthritis or Degenerative Joint Disease manner as the complete blood cell count, the synovial fluid should be treated with hyaluronidase before preparing a thin or cytocentrifuged slide for the differential. If hyaluronidase is omitted, the cells will be too condensed and dark to make an accurate identification on a Wright stain. Some synovial fluid CCBF : Body fluids, other than the commonly analyzed urine and blood, include synovial, pleural, peritoneal, and pericardial fluids. These fluids may be present in increased volumes and may contain increased numbers of normal and abnormal cells in a variety of disease states

Synovial (joint) fluid analysis: Procedure and result

WBC count is one the most frequent tests performed on synovial fluid. Normally, synovial fluid contains less than 200 cells/µL. This count increases significantly in infections and inflammation... Abstract. OBJECTIVE To determine the precision and agreement of synovial fluid (SF) cell counts done manually and with automated counters, and to determine the degree of variability of the counts in SF samples, kept in the tubes used for routine white blood cell (WBC) counts—which use liquid EDTA as anticoagulant—at 24 and 48 hours at 4°C, and at room temperature Synovial fluid analysis test checks for presence of bacterial infection in an inflamed joint. Watch as Dr. Ankush explains about synovial fluid, its usage, t.. In the clinical laboratory, the reference method for counting the number of WBC in synovial fluid is by the use of a cytometer and a microscope [ 1 ]. Surprisingly, and in contrast to its central place in the diagnosis of arthritis, the reliability of this test has been little studied Unfortunately, synovial fluid analysis rarely is specific for an underlying cause. Thus, the fluid is usually classified as being non-inflammatory (degenerative joint disease or trauma) or inflammatory, based on the nucleated cell count, total protein, viscosity, types of cells and appearance of cells in the fluid (see algorithm)

When a LOINC term with the System Body fld is used, the specific specimen source or body fluid type should be reported elsewhere with the result Synovial fluid white blood cell (WBC) counts may not be the most optimal method to differentiate septic arthritis from arthritis caused by Lyme disease, according to findings from a new study published in Pediatrics.For a more accurate diagnosis of Lyme disease, newer-generation diagnostics are needed to avoid both underdiagnosis and overdiagnosis of Lyme disease to plan appropriate management We conclude that synovial fluid white blood cell count and percentage of polymorphonuclear cells perform well as discriminators between inflammatory and noninflammatory disease. Ordering chemistry studies of synovial fluid should be discouraged because they are likely to provide misleading or redundant information. (JAMA. 1990;264:1009-1014

The procedure is also called joint fluid aspiration, joint tap, synovial fluid aspiration, etc. Joint aspiration is typically performed as an in-office procedure. The most common indication for the procedure is a condition called arthritis - a group of diseases affecting joints or their component tissues Tube 2 had 200 µL of synovial fluid and was pretreated with hyaluronidase for testing on the Beckman Coulter Iris iQ200. The sample was diluted according to sample appearance . TNC and RBC counts were recorded. Tube 3 had 500 µL of synovial fluid and was manually assessed by hemocytometer, according to standard operating procedure (10, 11. Large amounts of fluid can be removed to alleviate discomfort. Synovial Fluid (Arthrocentesis): Synovial fluid is a colorless or pale yellow, transparent, and viscous liquid found in the joint cavities. Although synovial fluid is found in all joints, the specimen frequently received in the laboratory is an aspirate of the knee

The cell count is usually higher than 50,000 WBC/µL (with polymorphonuclear leukocytes [PMNs] typically accounting for more than 90%). Synovial fluid with this much inflammation may appear purulent. Gram-negative intracellular organisms may be demonstrated, albeit in less than 25% of synovial fluid aspirates Synovial fluid, also called synovia, is a viscous, non-Newtonian fluid found in the cavities of synovial joints.With its egg white-like consistency, the principal role of synovial fluid is to reduce friction between the articular cartilage of synovial joints during movement. Synovial fluid is a small component of the transcellular fluid component of extracellular fluid Body fluid cell count has been part of the hematology laboratory and remains a time-consuming manual task for technologists. The cell count test provides valuable information to clinicians in the diagnosis and treatment of a various medical conditions. Albeit the diagnostic prowess of cell counts, there has also been an intrapersonnel variation in counts tha Appropriate containers for collection of fluid for laboratory tests (eg, cell count, crystals, cultures) For intra-articular therapeutic injection, a syringe containing a corticosteroid (eg, triamcinolone acetonide 40 mg or methylprednisolone acetate 40 mg) and/or a long-acting anesthetic (eg, 0.25% bupivacaine ), and a hemostat to help switch.

Synovial fluid associated with septic or infectious joint effusion is as follows: Total white blood cell count higher than 25,000/microliter (approximately 75% sensitive, 75% specific) Total white blood cell count higher than 50,000/microliter (approximately 60% sensitive, approximately 90% specific 74689-1 Nucleated cells [#/volume] in Body fluid by Manual count Active Part Descriptions. LP65367-2 Nucleated cells Nucleated cells are defined as any cell with a nucleus; the types of nucleated cells present depend on the specimen source. White blood cells are a common type of nucleated cell and can be further broken down into types of white blood cells (e.g., neutrophils, lympohcytes. Synovial Fluid. Removal of synovial fluid from the affected joint for testing serves not only as a diagnostic procedure, but also as a treatment approach, because it reduces pressure in the joint. Synovial fluid should be analyzed using cell count, gram stain, and culture. Elevated synovial white blood cell (WBC) count is highly suggestive of.
