e to CBC Machine: Working, Parts & Common Problems



---


1. Introduction


In modern healthcare, accurate diagnosis is essential for proper treatment. One of the most commonly used laboratory tests is the Complete Blood Count (CBC), which helps doctors understand a patient’s overall health condition.


A CBC machine plays a crucial role in analyzing blood samples quickly and accurately. It is widely used in hospitals, diagnostic labs, and clinics to measure different components of blood.


This article will help you understand what a CBC machine is, how it works, its main parts, and common problems faced during operation.

2. CBC Machine kya hoti hai


A CBC machine (Complete Blood Count analyzer) is a laboratory device used to analyze blood samples and measure different blood parameters.


👉 It mainly measures:


✔ RBC (Red Blood Cells)

✔ WBC (White Blood Cells)

✔ Platelets

✔ Hemoglobin (HGB)

✔ Hematocrit (HCT)


This machine helps doctors detect diseases like anemia, infections, and other blood-related disorders.


CBC machines can be:


👉 Semi-automatic

👉 Fully automatic


Modern CBC analyzers provide fast, accurate, and reliable results within a few minutes.

3. Working kaise karti hai


CBC machine works on different scientific principles depending on the model. The most common principles are:


👉 Electrical impedance

👉 Flow cytometry

👉 Light scattering


Working Process:


1. Blood sample is collected from the patient

2. Sample is mixed with reagent

3. Sample passes through a small aperture

4. Cells are counted and analyzed

5. Data is processed by the system

6. Final report is generated


👉 Example:


When blood cells pass through the aperture, they create electrical resistance changes, which are counted as cells.


This method helps in accurate counting of RBC, WBC, and platelets.
