Lupus Diagnosis: Quick and Reliable Test to Find Answers Today

Lupus Diagnosis is a chronic autoimmune disease causing body-wide inflammation. Its cause is unknown, but genetics and environment may contribute. Symptoms include fatigue, joint pain, rashes, and organ damage.

 

Lupus Diagnosis involves tests and symptom evaluation. No cure exists, but treatment can improve quality of life. Early detection and care enhance outcomes for lupus patients.

Interpretation	A positive result indicates lupus presence, especially SLE.

The Anti-Smith (Sm) Antibody Test detects lupus, specifically systemic lupus erythematosus (SLE), through antibody measurements. It is accurate and performed on a blood sample during disease flares.

 

4. Anti-Ro (SSA) and Anti-La (SSB) Antibody Tests

• Helps detect specific antibodies associated with Lupus and Sjögren's syndrome.
• Detects antibodies related to Lupus and Sjögren's syndrome, aiding in diagnosis.
• The presence of these antibodies in pregnant women can pose risks to the baby's heart and skin.

Anti-Ro and Anti-La Antibody Tests	Details
Also Known As	Ro/SSA and La/SSB Antibody Tests
Purpose	Detect specific antibodies associated with lupus
Sample	Blood
Preparation	Fasting
Procedure	Blood draw and laboratory analysis
Test Timing	1-3 days
Test Price (INR)	500-2000
Result Value	Reported as antibody presence or absence
Normal Value	Negative
Accuracy	Moderate sensitivity
Interpretation	A positive result indicates the presence of specific antibodies.

The Anti-Ro (SSA) and Anti-La (SSB) Antibody Tests detect specific antibodies associated with lupus diagnosis and autoimmune conditions. They are accurate blood tests with results indicating the presence or absence of antibodies.

 

5. Complete Blood Count (CBC)

• CBC measures red and white blood cells, hemoglobin, and platelets.
• It helps detect anemia, infections, and abnormal cell counts.
• CBC aids in monitoring disease progression and treatment effectiveness.

Complete Blood Count	Details
Also Known As	CBC, Blood Count
Purpose	Assess overall blood health
Sample	Blood
Preparation	Fasting may not be required
Procedure	Blood draw and laboratory analysis
Test Timing	2-4 hours
Test Price (INR)	200-1000
Result Value	Various blood cell counts and parameters
Normal Value	Varies based on age, sex, and health
Accuracy	General screening tool
Interpretation	Abnormalities may indicate underlying conditions.

The Complete Blood Count (CBC) assesses overall blood health by analyzing various blood cell counts and parameters. It is a widely used test with high accuracy and can provide insights into underlying conditions based on abnormalities.

 

6. Erythrocyte Sedimentation Rate (ESR)

• ESR measures inflammation levels in the body.
• Increased ESR indicates disease activity or infection.
• ESR is a non-specific test used in Lupus diagnosis and monitoring.

Erythrocyte Sedimentation Rate	Details
Also Known As	Sed Rate
Purpose	Measure inflammation levels in the body.
Sample	Blood
Preparation	None
Procedure	Blood draw and laboratory analysis
Test Timing	1-2 hours
Test Price (INR)	100-500
Result Value	Reported as mm/hour
Normal Value	Varies by age and gender
Accuracy	Nonspecific inflammation indicator
Interpretation	The increased rate indicates inflammation.

The Erythrocyte Sedimentation Rate (ESR) test measures inflammation levels in the body through a simple blood draw. It provides valuable information about the presence of inflammation, helping in the diagnosis of various conditions.
