ITP Diagnosis: Essential Tests for Immune Thrombocytopenic Purpura

Immune Thrombocytopenic Purpura (ITP) is an immune system disorder causing a low platelet count, resulting in abnormal bleeding. ITP Diagnosis involves blood tests and proper management improves outcomes.

 

6 Tests for ITP Diagnosis

Accurate diagnosis of Immune Thrombocytopenic Purpura (ITP) is crucial to provide appropriate treatment and manage potential complications.

 

The tests commonly used for diagnosing Immune Thrombocytopenic Purpura (ITP) include:

1. Complete blood count (CBC)
2. Peripheral blood smear
3. Biopsy
4. Coagulation studies
5. H. pylori testing
6. Reticulated platelet count

 

 

1. Complete Bood Count (CBC)

• Measures platelet count, red blood cells, and white blood cells.
• Provides important information about overall blood health.
• Helps diagnose conditions such as anemia, infections, and immune disorders.

Interpretation	Abnormal values may indicate certain conditions or disorders

Complete Blood Count (CBC) is a widely used blood test that evaluates overall blood health, detects abnormalities, and aids in ITP diagnosis.

 

2. Peripheral Blood Smear

• Examines a sample of blood under a microscope.
• Evaluates the morphology and characteristics of blood cells.
• Helps detect abnormalities such as abnormal platelet count, infections, and blood cell disorders.

Interpretation	Identifies abnormal cell shapes, sizes, and quantities

Peripheral Blood Smear (Blood Film) is a microscopic test that assesses blood cell morphology, detects abnormalities, and aids in ITP diagnosis.

 

3. Biopsy

• Involves taking a tissue sample for further examination.
• Helps diagnose and determine the extent of diseases or abnormalities.
• Commonly performed on organs such as the liver, bone marrow, or lymph nodes.

Biopsy	Details
Also Known As	Tissue biopsy
Purpose	Obtain tissue sample for diagnosis
Sample	Tissue

Test Timing	Varies
Test Price (INR)	5000-15000
Result Value	Histopathological findings
Normal Value	N/A
Accuracy	Tissue examination
Interpretation	Assists in diagnosing various conditions, determining the extent of diseases

Biopsy is a surgical procedure to obtain tissue samples for ITP diagnosis. It provides accurate histopathological findings and aids in determining disease extent.

 

4. Coagulation Studies

• Assesses the blood's ability to clot and the function of clotting factors.
• Helps diagnose and monitor bleeding disorders or abnormal clotting tendencies in ITP diagnosis.
• Includes tests like prothrombin time (PT), activated partial thromboplastin time (aPTT), and thrombin time (TT).

Coagulation Studies	Details
Also Known As	Clotting tests
Purpose	Assess blood clotting, detect bleeding disorders
Sample	Blood
Preparation	Fasting
Procedure	Assess bleeding risk
Test Timing	2-4 hours
Test Price (INR)	1000-5000
Result Value	Clotting factor levels
Normal Value	Varies
Accuracy	Reliable coagulation assessment
Interpretation	Identifies clotting factor deficiencies, abnormalities, or bleeding disorders

Coagulation Studies (Clotting Tests) assess blood clotting ability, detect bleeding disorders, and identify clotting factor deficiencies or abnormalities.

 

5. H. pylori Testing

• Checks for the presence of Helicobacter pylori bacteria in the stomach.
• Helps in ITP diagnosis H. pylori infection, a common cause of gastritis and stomach ulcers.
• Can involve breath tests, blood tests, or stool tests to detect H. pylori antibodies or antigens.

H. pylori Testing	Details
Also Known As	Helicobacter pylori testing
Purpose	Detect H. pylori infection
Sample	Breath, blood, or stool
Preparation	Fasting
Procedure	Various tests detect H. pylori antibodies or antigens in the sample
Test Timing	2-4 hours
Test Price (INR)	500-2000
Result Value	Presence or absence of H. pylori bacteria
Normal Value	Negative for H. pylori presence
Accuracy	Accurate bacterial detection
Interpretation	A positive result indicates H. pylori infection, negative result indicates its absence

H. pylori Testing detects presence of H. pylori bacteria, a common cause of gastritis and ulcers. Highly accurate for ITP diagnosis.

 

6. Reticulated Platelet Count

• Measures the number of young, immature platelets in the blood.
• Indicates the rate of platelet production by the bone marrow.
• Useful in evaluating platelet production disorders and monitoring response to treatment.

Reticulated Platelet Count	Details
Also Known As	Reticulocyte platelet count
Purpose	Measure the number of young, immature platelets
Sample	Blood
Preparation	None
Procedure	Blood sample is analyzed
Test Timing	2-4 hours
Test Price (INR)	500-2000
Result Value	Percentage of reticulated platelets
Normal Value	Reference range
Accuracy	Precise platelet evaluation
Interpretation	Helps assess platelet production disorders and response to treatment

Reticulated Platelet Count measures immature platelets in the blood, aiding in assessing platelet production disorders. Accurate and informative for ITP diagnosis and treatment response.
