What is Peripheral Blood Smear Evaluation in Hematology?

Peripheral blood smear examination remains a fundamental hematologic test that complements automated counters by revealing morphologic features no instrument detects. Trained reviewers inspect red cell size, shape, and inclusions, white cell differential and maturation, and platelet number and clumps.

Red cell findings include microcytosis with hypochromia in iron deficiency, macroovalocytes in megaloblastic anemia, schistocytes in microangiopathic hemolysis, sickle cells in hemoglobinopathy, target cells in liver disease, and spherocytes in hereditary or autoimmune hemolysis. White cell findings include left shift, blasts, hypersegmented neutrophils, and atypical lymphocytes.

Platelet findings include true thrombocytopenia, pseudothrombocytopenia from clumps, large platelets in immune thrombocytopenia, and giant platelets in inherited disorders. Smear review accelerates diagnosis of leukemia, microangiopathy, and parasitic infection and triggers urgent reflex testing.

Symptoms

Pallor and fatigue with anemia
Easy bruising with platelet disorders
Fever and night sweats with leukemia
Jaundice with hemolytic disease
Recurrent infections with neutropenia

Risk Factors

Inherited hemoglobinopathy or membrane disorder
Exposure to drugs causing immune cytopenia
Recent travel to malaria endemic regions
Mechanical heart valve or microangiopathy risk
Chemotherapy or radiation history

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • When unexplained cytopenia is detected
  • When automated counters flag morphology
  • When schistocytes are identified
  • When blasts appear on smear
  • When parasitic infection is suspected

Treatment Methods

01
Air dried Wright Giemsa stained smear
02
Examination of feathered edge for morphology
03
Reflex iron and reticulocyte testing as needed
04
Direct antiglobulin test for hemolysis
05
Hemoglobin electrophoresis when indicated
06
Bone marrow examination for blasts
07
Disease specific therapy guided by findings

Anaemia

Dahiliye (İç Hastalıkları)

Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.

Iron Deficiency Anaemia

Dahiliye (İç Hastalıkları)

Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.

Vitamin B12 Deficiency

Dahiliye (İç Hastalıkları)

Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.

Hypertension (High Blood Pressure) Management

Dahiliye (İç Hastalıkları)

Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.

Chronic Kidney Disease

Dahiliye (İç Hastalıkları)

Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.

Hepatitis B (HBV)

Dahiliye (İç Hastalıkları)

Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.

Hepatitis C (HCV)

Dahiliye (İç Hastalıkları)

Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.

Fatty Liver Disease

Dahiliye (İç Hastalıkları)

Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
