The Anti-CCP Test identifies RA-related antibodies. A positive result suggests potential Rheumatoid arthritis presence.

 

3. Erythrocyte Sedimentation Rate (ESR) Test

• Measures the rate at which red blood cells settle in a tube.
• Elevated levels indicate inflammation, including Rheumatoid arthritis.
• Helps in rheumatoid arthritis diagnosis and monitoring disease activity and response to treatment.

Erythrocyte Sedimentation Rate (ESR) Test	Details

Sample	Blood
Preparation	None
Procedure	Blood draw
Test Timing	1 hour
Test Price (INR)	100-500
Result Value	Measured in millimeters per hour (mm/hr)
Normal Value	Varies by age, gender
Accuracy	Moderate
Interpretation	Elevated levels indicate inflammation presence

The ESR Test measures inflammation levels through blood. Elevated levels indicate potential inflammation presence.

 

4. C-reactive Protein (CRP) Test

• Measures the level of CRP in the blood, a marker of inflammation.
• Elevated CRP levels indicate active inflammation, including Rheumatoid arthritis.
• Helps in rheumatoid arthritis diagnosis for assessing disease activity, monitoring treatment response, and predicting prognosis.

C-reactive Protein (CRP) Test	Details
Also Known As	CRP blood test
Purpose	Measures inflammation levels
Sample	Blood
Preparation	None
Procedure	Blood draw
Test Timing	2-4 hours
Test Price (INR)	200-1000
Result Value	Milligrams per liter (mg/L)
Normal Value	<10 mg/L
Accuracy	Moderate
Interpretation	Elevated levels indicate inflammation presence

The C-reactive Protein (CRP) Test measures inflammation levels through a blood sample. Elevated levels indicate the presence of inflammation in the body.

 

5. Complete Blood Count (CBC)

• Provides information about various blood components, including red and white blood cells.
• Can detect anemia, which is common in Rheumatoid arthritis.
• Helps in rheumatoid arthritis diagnosis for assessing overall health, detecting infections, and monitoring treatment effects.

Complete Blood Count (CBC) Test	Details
Also Known As	CBC, Hemogram
Purpose	Evaluates overall blood health
Sample	Blood
Preparation	None
Procedure	Blood draw
Test Timing	2-4 hours
Test Price (INR)	200-1000
Result Value	Various blood component counts
Normal Value	Varies based on blood component
Accuracy	High
Interpretation	Abnormal values may indicate certain conditions or disorders

The CBC Test evaluates overall blood health. Abnormal values may indicate potential conditions or disorders.

 

6. Joint Fluid Analysis

• Involves examining fluid extracted from an affected joint.
• Helps differentiate between different types of arthritis, including Rheumatoid arthritis.
• Assists in rheumatoid arthritis diagnosis of joint inflammation, infection, or injury, guiding appropriate treatment.

Joint Fluid Analysis	Details
Also Known As	Joint aspiration, Arthrocentesis
Purpose	Evaluates joint infection
Sample	Synovial fluid
Preparation	None
Procedure	Joint fluid extraction through a needle
Test Timing	A few hours
Test Price (INR)	500-2000
Result Value	Analysis of fluid appearance
Normal Value	Clear or straw-colored fluid
Accuracy	High
Interpretation	Helps diagnose conditions like arthritis or joint infections

Joint Fluid Analysis evaluates joint inflammation or infection using synovial fluid. It aids in diagnosing conditions like arthritis or joint infections based on fluid analysis.

Rheumatoid Arthritis (RA)	Positive rheumatoid factor and anti-CCP antibodies.
Psoriatic Arthritis	Presence of psoriasis and characteristic nail changes.
Systemic Lupus Erythematosus (SLE)	Positive ANA, anti-dsDNA, or other autoantibodies.
Osteoarthritis	Absence of systemic features and specific autoantibodies.
Sjögren's Syndrome	Positive anti-SSA/SSB antibodies.

Rheumatoid arthritis differential diagnosis involves distinguishing it from similar conditions like osteoarthritis, lupus, psoriatic arthritis, gout, Sjögren's syndrome, ankylosing spondylitis, reactive arthritis, and rheumatic fever using specific differentiating factors.
