Complete blood count (CBC) with differential and ESR

Hematology panel: Complete blood count

Complete blood count (CBC) — is a basic study that we conduct in the Medi Lab Plus laboratory network using modern automatic analyzers. This approach ensures the accuracy of each indicator: from standard hemoglobin and erythrocytes to specific parameters of the leukocyte panel. Double control (automatic calculation + manual calculation of the leukocyte formula) allows our specialists to detect the slightest deviations from the norm in the early stages.

What indicators are included in the study:

• Erythrocyte panel: RBC (red blood cells), Hb (hemoglobin), Hct (hematocrit), erythrocyte indices (MCV, MCH, MCHC), RDW (red blood cell distribution width), 3 graphical histograms.
• White blood cell panel and manual count: WBC (leukocytes), absolute and percentage content of leukocyte subpopulations (Lym, Mid, Grn / Lym %, Mid %, Grn %), manual calculation of leukocyte formula.
• Platelet panel: Plt (platelets), platelet indices (Pct, MPV, PDW).
• ESR (erythrocyte sedimentation rate).

How to prepare for a complete blood count (CBC)

• Capillary (from a finger) or venous blood is used for the study.
• Blood should be donated in the morning on an empty stomach, after an overnight fast (8–12 hours). The day before, do not consume alcohol, fatty or spicy foods.
• If you are taking medications, consult your doctor about the appropriateness of performing a CAC during this period.
• Blood should be donated before diagnostic procedures (ultrasound, X-ray, physiotherapy, etc.).
• It is not recommended to take blood samples immediately after physical or emotional stress.
• You should refrain from smoking in the morning after getting up.
• Immediately before blood sampling, you should rest for 10–15 minutes at rest.
• On the day of the study, it is permissible to drink a small amount of still water.
• To monitor indicators over time, it is important to adhere to the same conditions during repeated studies.
• In case of emergency, it is allowed to submit the ZAK without prior preparation.

Detailed interpretation of blood test results

1. WBC (white blood cells): WBC, or white blood cells, refers to the number of white blood cells in one microliter of blood. They play an important role in fighting infections and inflammation. An increase in this number may indicate infection or inflammation, while a decrease may be a sign of immunodeficiency conditions.
2. Lym, Mid, Grn (lymphocytes, monocytes, granulocytes): These indicators indicate the content of different types of white blood cells in your blood. Particular attention should be paid to the MID (or MXD) indicator. If the MID indicator in the blood is elevated, this may be a sign of an allergic reaction, parasitic infections or the beginning of an inflammatory process. Accurate interpretation MID along with WBC and Lym allows the doctor to determine the cause of the illness with high accuracy.
3. Lym %, Mid %, Grn % (percentage of lymphocytes, monocytes, granulocytes): These numbers indicate the percentage of different types of white blood cells. They help to understand which part of the immune system is working most actively.
4. RBC (red blood cells): Red blood cells that carry oxygen. A decrease in this number can be a sign of anemia, while an increase can indicate other disorders.
5. Hb (hemoglobin): The component of red blood cells that carries oxygen. A decrease in Hb may indicate anemia or problems with blood formation.
6. Hct (hematocrit): It measures the volume of red blood cells in the blood. A high hematocrit can be a sign of dehydration, while a low one can indicate anemia.
7. MCV, MCH, MCHC (erythrocyte indices): These indicators help determine the size and hemoglobin content of red blood cells, which is important for diagnosing various types of anemia.
8. RDW (red blood cell distribution width): Indicates a difference in the size of red blood cells. An increase in RDW may be a sign of iron or vitamin deficiency.
9. Plt (platelets): Responsible for blood clotting. Changes in this indicator may indicate a risk of bleeding or thrombosis.
10. Pct, MPV, PDW (platelet indices): Platelet characteristics indicating their average volume and size distribution, which is important for assessing the state of the coagulation system.

Additionally, manual analysis can be performed in hematology analysis. calculation of leukocyte formula by age and determination of ESR (erythrocyte sedimentation rate), which helps identify certain types of leukocytes and their quantitative characteristics.

Hematology analysis is an important tool for diagnosing various diseases and health conditions. The results of this analysis help doctors prescribe the right treatment and monitor the effectiveness of the patient's treatment.
