What does a high total nucleated cell count mean?
What does nucleated cell count mean? The presence of nucleated RBC can indicate a number of diseases or blood conditions, such as leukemia, anemia, or problems with the spleen. A count of nucleated RBC might suggest that the body is so desperate for red blood cells that it has begun producing them outside of the bone marrow.
What are total nucleated cells?
The Total Nucleated Cell count or TNC is the test most often reported as a measure of the cell count after cord blood processing. The main advantage of measuring TNC is that the count is highly reproducible within and among labs, so it can be used accurately throughout the blood banking community.

What is nucleated cell count in CSF?
- Low number is normal.

What does a high nucleated cell count in synovial fluid mean?
White or light yellow coloration or sediment indicates an increase in the nucleated cell count because of inflammation, sepsis, or neoplasia, or it may indicate crystal formation.
What is the most likely diagnosis associated with this synovial fluid?
If your results show your synovial fluid was not normal, it may mean one of the following conditions: A type of arthritis, such as osteoarthritis, rheumatoid arthritis, or gout. Bleeding disorder. Bacterial infection.
What does abnormal synovial fluid mean?
Abnormal synovial fluid may be cloudy and thicker or thinner than normal fluid. Cloudiness could mean there are crystals, excess white blood cells, or microorganisms in the fluid. If you have gout, the fluid will contain crystals. Less stringiness in the fluid could signal inflammation.
How do you interpret synovial fluid results?
Normal synovial fluid is clear and colorless or straw-colored. Abnormal fluid may look cloudy, opaque, and/or differently colored. For example, cloudy fluid may indicate an infection, and pink or reddish fluid may indicate the presence of blood.
What is cell count in synovial fluid?
Normally, synovial fluid contains less than 200 cells/µL. This count increases significantly in infections and inflammation.
What cells are in synovial fluid?
Synovial fluid is produced as an ultrafiltrate of blood plasma and is primarily composed of hyaluronan, lubricin, proteinase, collagenases, and prostaglandins. [1] Synovial fluid production is from fibroblast like type B synovial cells.
Which synovial fluid analysis findings are suggestive of rheumatoid arthritis?
Analysis of synovial fluid includes Gram staining, cell count, culture, and assessment of overall appearance. In patients with RA, analysis typically reveals inflammation (white blood cell [WBC] count >2000/µL, generally in the range of 5000-50,000/µL).
Which diagnostic procedure detects abnormalities in synovial fluid?
Synovial fluid analysis procedure During a synovial fluid analysis, a doctor will extract and analyze a sample of synovial fluid from the joint. Doctors may refer to the collection of synovial fluid as arthrocentesis.
What are the symptoms of septic arthritis?
Key points about septic arthritis Symptoms include fever, joint pain, swelling, redness, and warmth. Quick treatment with antibiotics is needed to halt the risk of joint damage. Other treatments include medicines for pain and fever, drainage of the joint, physical therapy, and a splint.
What does a high nucleated cell count mean?
A positive nucleated red blood cell (NRBC) count may indicate that the individual has leukemia.
What happens to synovial fluid in rheumatoid arthritis?
As rheumatoid arthritis progresses, the synovium, which produces synovial fluid, swells and thickens, producing an excess of synovial fluid. This, in turn, leads to further swelling and inflammation which causes pain and stiffness in the joint.
What happens to synovial fluid in osteoarthritis?
During osteoarthritis, synovial fluid becomes less viscous and these inflammatory substances come into direct contact with sensory nerve cells in the joint, producing the sensation of pain.
What is synovial fluid?
Synovial fluid is the thick liquid that lubricates your joints and keeps them moving smoothly. It’s on all of your joints, including in your knees, shoulders, hips, hands, and feet. Joint conditions like arthritis, gout, infections, and bleeding disorders can change how your synovial fluid looks and feels. A sample of this fluid taken ...
What is synovial fluid analysis?
What Is a Synovial Fluid Analysis? A synovial joint fluid analysis is a group of tests your doctor can use to diagnose problems with your joints. Joint conditions like arthritis, gout, infections, and bleeding disorders can change how your synovial fluid looks and feels.
What is the disease that breaks down joints over time?
An infection like septic arthritis. Bleeding disorders like hemophilia or von Willebrand disease. A disease that break down joints over time, like osteoarthritis. Your doctor might also use this test to see if your treatment for your joint condition is working.
How to check fluids?
Check your fluid's color and thickness. Measure chemicals like glucose, protein, and uric acid. See how many red and white blood cells and crystals your fluid has. Test for bacteria, viruses, or other germs.
Can a synovial fluid test help you?
If you have joint symptoms like: Synovial fluid analysis can also help your doctor figure out if you have: Your doctor might also use this test to see if your treatment for your joint condition is working. If your doctor thinks you need this test, ask them how to prepare.
What is the lubricant produced by synovial fluid?
Joints are lubricated by synovial fluid, produced by specialized lining cells, called synoviocytes. The cells produce hyaluronic acid as well as other constituents of synovial fluid, including glycosaminoglycans. These proteins impart viscosity to the fluid, which is subjectively assessed as part of synovial fluid analysis.
What is normal joint fluid?
Smear assessment: Normal joint fluid is viscous and of low cellularity. Cells are comprised of 50-90% mononuclear cells, of which 80% or more are macrophages or synovial lining cells with <20% lymphocytes. There are usually <10% neutrophils (non-degenerate).
What is the purpose of hyaluronidase in labs?
Most laboratories perform nucleated cell counts , red blood cell (RBC) counts , an estimate of viscosity, and cytologic smear assessment. Hyaluronidase can be added to fluids with very high viscosity that gel within the tube (called thixotropism), however this is not routinely done.
Why is a red top tube not indicated?
A red top or non-anticoagulant tube is not usually indicated, because biochemical analyses are not usually performed on synovial fluids. A culturette is preferred to a non-anticoagulant tube, if culture is anticipated or desired. Sometimes only enough fluid is aspirated to make 2-3 smears.
How long does inflammation last after a mesenchymal stem cell injection?
Similarly, injection of allogeneic or autologous mesenchymal stem cells results in a marked leukocytosis, consisting primarily of neutrophils, in injected joints (in contrast to minimal inflammation in a saline control) 24-48 hours after injection, with inflammation persisting for up to 72 hours after injection.
Does blood contamination increase neutrophils?
Blood contamination will falsely increase the total nucleated cell count (blood-associated leukocytes; their contribution will depend on the peripheral leukocyte count), total protein and % of neutrophils and will decrease viscosity. The degree to which blood influences these results is entirely subjective (opinion of clinical pathologist). In a freshly prepared sample, there will be platelets and no evidence of erythrophagia, however peracute hemorrhage can look similar. Thus, examination of the fluid during collection is the best way to assess for overt blood contamination (but will miss microscopic contamination). Erythrophagia does not provide additional information in smears made from stored fluid, because macrophages will phagocytize erythrocytes in the tube in vitro, particularly if activated (this can occur rapidly, within 2 hours, of collection).
Is neutrophil count high in sepsis?
Total nucleated cell counts and protein are usually high (>5,000/uL and >3.0 g/dL, respectively) but can be within normal limits) and viscosity can be normal or decreased (more often decreased with sepsis than immune-mediated disease). Concurrent hemorrhage may be seen.
