What is Evaluation of Coagulopathy in Hematology?

Coagulopathy refers to any abnormality of blood clotting that increases bleeding risk. Evaluation begins at the bedside: a structured bleeding history (Bleeding Assessment Tool), drug review, and family history are more sensitive than any single laboratory test. Routine screening tests are PT, aPTT, fibrinogen, and platelet count.

When PT or aPTT is prolonged, mixing studies separate factor deficiency from inhibitor: correction with normal plasma points to deficiency, while persistent prolongation suggests an inhibitor such as a lupus anticoagulant or acquired factor VIII inhibitor. Specific factor assays then localize the defect to factors II, V, VII, VIII, IX, X, XI, or fibrinogen.

Acquired causes are common and must be sought before chasing rare disorders: vitamin K deficiency, liver disease, disseminated intravascular coagulation (DIC), anticoagulant drugs, and massive transfusion all produce mixed coagulopathy. Acquired hemophilia A, although rare, carries high mortality and is recognized by an isolated prolonged aPTT with severe bleeding.

Symptoms

Easy bruising disproportionate to trauma
Mucosal bleeding such as gum bleeds and epistaxis
Heavy menstrual bleeding
Postoperative bleeding lasting beyond expected time
Hematuria or gastrointestinal bleeding
Joint bleeds (suggest hemophilia)

Risk Factors

Liver disease
Anticoagulant or antiplatelet therapy
Recent major surgery, trauma, or sepsis (DIC)
Pregnancy or postpartum (acquired hemophilia)
Underlying autoimmune disease or malignancy

When to See a Doctor?

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

  • Sudden severe bruising or hematomas without clear cause
  • Heavy bleeding from a small wound or after a tooth extraction
  • Postpartum bleeding that is unusually prolonged
  • New bleeding tendency in older adult

Treatment Methods

01
Treat the underlying cause: vitamin K, liver support, DIC management
02
Specific factor concentrate for inherited deficiency
03
Bypassing agents (FEIBA, recombinant factor VIIa) for acquired hemophilia A
04
Tranexamic acid for mucosal bleeding
05
Reverse anticoagulants when appropriate (idarucizumab, andexanet)
06
Avoid unnecessary plasma transfusion in stable patients
07
Hematology referral for any unexplained coagulopathy

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.
