What is a Synovial Fluid Analysis Chart?

A synovial fluid analysis chart is a crucial medical tool for diagnosing joint-related conditions like arthritis, more specifically, septic or crystal-induced arthritis. The diagnosis technique involves examining the synovial fluid, which nourishes and lubricates the joints, to determine the root cause of joint problems. The results aid with a comprehensive assessment for diagnosis. 

On the chart, particularly our template, you’ll find a table of the primary components of synovial fluid analysis, such as the white cell count, differential count, cultures, Gram stain, crystals, and more. These parameters aid in identifying the presence of infection, inflammation, or crystals in the joint fluid, which can significantly aid in diagnosing arthritis and related conditions. 

With the components mentioned above, the referring physician can categorize the joint fluid as noninflammatory, inflammatory, septic, or hemorrhagic by comparing the obtained values to the reference ranges on the chart.

One important note about synovial fluid analysis charts is that the reference ranges may vary between laboratories. One must consult local medical guidelines for specific reference values to ensure the accuracy of the analysis. 

How Does it Work?

Step One. Obtain a Printable Synovial Fluid Analysis Chart

To ensure prompt access to the chart, follow either of these steps:

  • Click the “Download Template” or “Use Template” button
  • Alternatively, you can find the “Synovial Fluid Analysis Chart” in Carepatron’s template library, available on both the website and the app

Step Two. Input Essential Information

If your purpose extends beyond using the chart merely as a visual aid for patient education on synovial fluid, it is advisable to complete the crucial patient details. This includes recording the results of the synovial fluid test. 

Step Four. Document Interpretations

Within our template, you can record your observations and findings in the designated space for result interpretation. Additionally, you can utilize this area to include any supplementary notes or information concerning required medical interventions or further examinations. 

Step Five. Securely Keep the Template

After completing the consultation, it is vital to securely store the template, allowing access only to relevant individuals. For digital copies, we recommend utilizing Carepatron, a HIPPA-compliant, free patient records software. Our platform can safeguard all medical records, including your completed synovial fluid analysis chart.

When Would you use this Test?

A synovial fluid analysis chart is a critical diagnostic tool used in various clinical scenarios to assess and manage joint-related. The decision to employ this chart is made under the following circumstances: 

Determining and Identifying Causes

When the patient experiences joint inflammation symptoms like pain, redness, swelling, or injury, and the cause is unexplained, the referring physician may request a synovial fluid test. Afterward, they can utilize the synovial fluid analysis chart template to gain insight into the joint disorder, its nature, and severity. 

For cases wherein the clinical situation is ambiguous, there’s a suspicion of infection, or observed fluid in a joint; the referring physician may also utilize the test and chart to pinpoint the cause or identify joint-related condition they may have. 


The synovial fluid analysis chart and the test results can be used as a basis for diagnosing two conditions: gout and arthritis. If a patient has gout, the test results and their interpretation will confirm the presence of uric acid crystals in the joint. Meanwhile, if the patient has arthritis, especially infectious, it will detect bacteria. 


Referring physicians caring for patients diagnosed with a known joint disorder may have the patient undergo periodic synovial fluid analysis and utilize the chart when monitoring their disease progression and the effectiveness of the treatment. Using the chart this way ensures that the chosen interventions provide the desired outcomes.

What do the Results Mean?

The results obtained from a synovial fluid test and interpreted using our free synovial fluid analysis chart template can offer critical insights into the state of a joint and can guide the diagnosis and management of joint-related conditions. 

Here’s a quick breakdown of what various results on the chart may signify:

Color and Clarity

Normal synovial fluid is typically clear and exhibits a straw-like color. Any deviation from this color may provide valuable information. If it’s cloudy, it suggests the presence of infection or inflammation within the joint. However, if it’s blood, it could indicate trauma to the joint or an underlying bleeding disorder. 

White Blood Cell (WBC) Count and Neutrophils

An elevated WBC in synovial fluid often indicates an ongoing infection or inflammation within the joint. If the patient has the aforementioned results, along with a higher percentage of neutrophils, it strongly suggests an active infection in the joint. 


The presence of crystals in the synovial fluid indicates different, specific types of arthritis. Uric acid crystals point towards gout, a type of inflammatory arthritis, while calcium pyrophosphate crystals are associated with pseudogout. 

Gram Stain and Culture 

If they test positive for a gram stain and culture, it means that the patient has bacteria or microorganisms responsible for undergoing joint infection.

Research & Evidence

While synovial fluid results may initially appear to be a more useful tool compared to synovial fluid analysis charts, it’s imperative to acknowledge that the absence of the latter would leave healthcare professionals without a reference point for identifying abnormal results, deficiencies, elevations, etc. in the results obtained. Therefore, it’s safe to say that both the results and their corresponding chart enhance the accuracy and precision of analysis and interpretation. 

While studies substantiating the use of synovial fluid analysis charts may be somewhat limited or even non-existent, the value of such charts can be discerned in their availability online and the appearance of variations in articles, journals, and reputable medical sources. So, to prove its utility, which is explicitly tied to the synovial fluid tests’ value, here are brief summaries of a report and an article that support and specify the use of the aforementioned test. 

According to a report published in the BMJ Research Forum, the synovial fluid test remains a valuable diagnostic tool for the following conditions: septic arthritis, crustal arthropathy, and intercritical gout. In addition to that, according to an article published on the National Library of Medicine website, through the synovial fluid, practitioners can also diagnose the following: inflammatory arthritis, hemorrhagic, and septic arthropathy. 

These two are among the many studies, journals, and articles that don’t only support synovial fluid testing but also its analysis, which is better done with the assistance of synovial fluid charts, which further support the use of charts when diagnosing, assessing, monitoring, etc.
