What is being analysed?

The red series is being analysed here, and it refers to the study and interpretation of the different parameters that study red blood cells. The main haematological parameters in peripheral blood are:

• Red blood cells
• Haemoglobin
• Haematocrit
• Mean corpuscular volume
• Mean corpuscular haemoglobin
• Mean corpuscular haemoglobin concentration
• Red cell distribution width
• Reticulocytes

Why is this analysis carried out?

The analysis of the red series index is one of the most commonly used diagnostic tests in routine medical practice. Current automatic analysers allow the determination of the main haematological parameters in peripheral blood with a high degree of reliability, speed, and low cost, providing valuable information about the three haematological series: red series, white series, and platelets.

When and why is this analysis done?

The analysis of the red series index is performed to evaluate the presence of anaemia, polycythaemia, bone marrow diseases, chronic diseases, infections, inflammations, among others.

What sample is required?

A peripheral blood sample is required.

Is any prior preparation necessary?

No prior preparation is required.

How is it used?

The analysis of the red series is used to evaluate the presence of anaemia, polycythaemia, bone marrow diseases, chronic diseases, infections, and inflammations.

What are the normal values?

The normal values of circulating red blood cells are around 5.5 ± 1 x 10¹²/l in men and 4.8 ± 1 × 10¹² /l in women. For an adequate assessment of the existence of anaemia or polycythaemia, it is necessary to determine the concentration of haemoglobin and haematocrit. The normal concentration of haemoglobin in blood in adults is 14 ± 2 g/dl in women and 16 ± 2 g/dl in men.

What does it mean to have altered values?

Altered values may indicate the presence of anaemia, polycythaemia, bone marrow diseases, chronic diseases, infections, inflammations, amongst other medical conditions.
