What is the normal value of synovial fluid?
Normally, synovial fluid contains less than 200 cells/µL. This count increases significantly in infections and 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 the normal amount of fluid in the knee joint?
The knee joint normally has less than 1 ounce of fluid. Injury or inflammation of the knee joint causes extra fluid to collect there. When this happens, the knee joint looks swollen and is often painful.
What is normal WBC in synovial fluid?
In crystal arthritis, the white blood cell (WBC) count in the synovial fluid is usually 10,000-70,000/µL. However, it may be as low as 1000/µL or as high as 100,000/µL. Even in the presence of crystals in the joint fluid, blood cultures are indicated if any sign of systemic toxicity is present.
What are the normal parameters of synovial fluid analysis?
Normal constituents of the synovial fluid:
| Features | Findings |
|---|---|
| Glucose | <10 mg/dL lower than the blood level |
| Total protein | <3 G/dL (1 to 3 G/dL) |
| Lactate | <250 mg/dL |
| Uric acid | This is equal to the blood level (male = 2 to 8 mg/dL and female = 2 to 6 mg/dL) |
What is mild synovial fluid?
Synovial fluid analysis is also known as joint fluid analysis. It helps diagnose the cause of joint inflammation. Each of the joints in the human body contains synovial fluid. This fluid is a thick liquid that lubricates the joint and allows for ease of movement.
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.
What is measured in synovial fluid?
Measures glucose, proteins, uric acid, and lactate dehydrogenase (LDH) Measures the concentration of cells in the fluid. Cultures the fluid to see if any bacteria grow.
How can I increase synovial fluid in my knee?
Some foods are very good for your joints, such as:
- Dark, leafy vegetables.
- Omega-3 fatty acids (found in salmon, mackerel, and flaxseeds)
- Anti-inflammatory foods that have curcumin in them (a compound found in turmeric)
- High antioxidant foods (onions, garlic, green tea, and berries)
- Nuts and seeds.
What does high WBC in synovial fluid mean?
The synovial fluid may be cloudy or thick. A high white blood cell count could mean you have an infection or another medical condition. A high uric acid level and crystals could signal gout. A high red blood cell count could result from: Injury.
What does high neutrophils in synovial fluid mean?
Rheumatoid arthritis (RA) is a chronic inflammatory disorder affecting synovial joints. Neutrophils are believed to play an important role in both the initiation and progression of RA, and large numbers of activated neutrophils are found within both synovial fluid (SF) and synovial tissue from RA joints.
Are your joints low on synovial fluid?
What would happen if there was no synovial fluid in your joints? When your fluid is low, it can stop the movement. When synovial fluid becomes too thick or too thin, it cannot provide the correct lubrication to protect the joints, which can lead to cartilage damage and osteoarthritis.
What does High nucleated cells in synovial fluid mean?
What does high nucleated cells 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 treatment for synovial fluid in the knee?
What you can expect following a hyaluronic acid injection? Hyaluronic acid can provide pain relief upto nine months to two years.
What is joint fluid analysis?
