Parasitology
Parasitology Challenge: Unknown Object in Urine Sediment
A diagnostic parasitology challenge: a motile microorganism, 130 µm long, was found in a native urine sediment preparation. Identify the object from the photos.
Hematology
Microscopy Exercise: Identify Three Blood Smear Cells
A practical exercise in laboratory hematology: microscopy of a peripheral blood smear and differentiation of three leukocytes based on their morphological features.
Lab test interpretation
Stool Microscopy Challenge: Identify the Finding
A clinical case study in stool microscopy: an unidentified structure in a Lugol's solution preparation. Determine the nature of the finding during coprological analysis.
Hematology
Radial Aggregation of Red Blood Cells in Peripheral Blood Smear
Unusual fan-shaped arrangement and aggregation of red blood cells in a blood smear: differential diagnosis of preparation artifacts and pathological clusters.
Lab test interpretation
Urine Sediment Microscopy: Identify the Elements
Diagnostic exercise on urine sediment microscopy in a pregnant woman: acidic reaction, protein 0.027 g/L. Identify elements in the microscope field of view.
Lab test interpretation
Gynecological Smear Microscopy: Identify the Object
A diagnostic challenge in flora smear microscopy: identify the origin of an unusual round structure found in two different patients.
Laboratory methods
Chylous Serum: Impact on Tests and Elimination Methods
What to do with pronounced chylous serum or plasma: methods for eliminating lipemic interference and rules for issuing laboratory test reports.
Lab test interpretation
Case Study: Cervical Canal Smear Microscopy
A diagnostic exercise in gynecological smear microscopy. Evaluate bacterial morphology in cervical canal discharge and identify the flora.
Parasitology
Morphology of Toxoplasma gondii Tachyzoites in Smears
Features of detecting Toxoplasma gondii tachyzoites in acute infection. Differential diagnosis of toxoplasmosis, histoplasmosis, and leishmaniasis in smears.
Hematology
Granulocyte Differentiation: From Promyelocyte to Mature Forms
Features of granulocytopoiesis: why promyelocytes do not differentiate by cell lines and at what stage of granulocyte maturation specific granules appear.
Parasitology
Parasitology Case: Brain Biopsy in Neurological Syndrome
Clinical case: acute neurological syndrome after consuming poultry. Examination of a brain biopsy smear and electron microscopy findings.
Lab test interpretation
Microscopy of a Flora Smear: Describing Bacteria
A diagnostic exercise on smear microscopy: identifying and correctly describing the morphology of bacterial flora in the form of characteristic rods.
