Reticulocytes, peripheral blood, brilliant cresyl blue stain.

Reference information. Reticulocytes are immature cells of the erythroid (red) hematopoietic lineage; they occupy an intermediate position between the oxyphilic erythroblast (normoblast) and the mature erythrocyte.

Autoimmune Hemolytic Anemia: Blood Smear Morphology

Wed, 25 Feb 2026 18:00:00 +0300

Autoimmune hemolytic anemia caused by warm antibodies

Polychromasia and spherocytes are found in the peripheral blood; circulating erythroblasts and occasional Howell-Jolly bodies may be present.

The disease is caused by immunoglobulin G class antibodies that react with red blood cells at temperatures of 37 degrees Celsius and above. This is the most common form of autoimmune hemolytic anemia.

Erythrocyte Inclusions: Cabot Rings & Howell-Jolly Bodies

🩸 Blood smear: details worth noting

🔹 Cabot rings – remnants of the mitotic spindle.

🔹 Howell-Jolly bodies – chromosome remnants in erythrocytes.

🔹 Basophilic stippling – RNA granules in the cytoplasm.

Blood Group Determination on the Shroud of Turin

Mon, 17 Apr 2023 10:52:14 +0300

✝THE SHROUD OF TURIN. What was JESUS CHRIST’s blood group?

🩸Early analyses showed the presence of iron oxide residues, indicating iron content in hemoglobin (the protein that gives red blood cells their red color), as well as a pigment with which medieval artists mixed iron. Forensic experts joined the discussion and were able to quite quickly confirm that the stains on the fabric were blood, and even determine the group - IV (fourth) 🆎.
