CDA Count – [whole blood EDTA]

Description

Cell Differential Analysis (CDA) quantifies the relative and absolute proportions of the five major white blood cell populations—neutrophils, lymphocytes, monocytes, eosinophils, and basophils—in peripheral blood. Performed on EDTA-anticoagulated whole blood, CDA provides critical insight into the body’s immune status and supports diagnosis and monitoring of infection, inflammation, allergic reactions, hematologic disorders, and immunodeficiency.

• Eosinophils
• Basophils
Specimen type Whole blood in K₂-EDTA tube (lavender top)
Collection & handling • Gently invert tube 8–10 times
• Analyze within 6 hours at room temperature
• Avoid clots and hemolysis
Assay methodology Automated hematology analyzer (optical scatter / impedance) with flagging for abnormal cell populations; manual smear review for flagged or critical differentials

Drink plenty of water before a urine sample collection for easier collection.
🔹 Pregnancy Test (Urine or Blood hCG Test)

A morning urine sample is preferred for the most accurate results.
For blood sample, no fasting is required.
🔹 Liver & Kidney Function Tests

Avoid alcohol and high-protein foods 12–24 hours before your sample collection.
Stay hydrated and avoid excessive exercise before the your sample collection.
🔹 ECG & CardiacTests

Avoid caffeine or energy drinks at least 3 hours before your sample collection.
Wear loose, comfortable clothing for easy placement of electrodes.
🔹 X-Ray & Imaging Tests

Remove any metallic items (jewelry, belts, etc.) before your sample collection.
Inform the radiologist if you are pregnant or suspect pregnancy.
🔹Sample Transportation

Samples are to be transported in a triple package format:

Wrap the primary sample container (I.e respective sample bottle EDTA, SST …)

Place the primary container uprightly in a water-tight secondary container (the secondary container could be a Falcon tube or something similar)

Place the secondary container into an outer package (A sample biohazard bag), while ensuring this bag is well sealed to preserve sample integrity.

Note all samples are expected to come with indicating patient name, Sex, Age, Test Required.

Blood samples will be transported on cold chain.

Swab samples will be transported on room temperature, that is it should not be placed on cold chain.
