🤔 What is the LFT..?

The Liver Function Test (LFT) is a diagnostic panel that evaluates the liver’s health by measuring specific enzymes, proteins, and bilirubin levels in the blood.


-------------------------------------------------------------------

🎯 Purpose of the Test

LFT is commonly used to:

• Detect liver infections (e.g. Hepatitis A, B, C)

• Monitor damage due to alcohol, drugs, or toxins

• Investigate jaundice, fatigue, or dark urine

• Track liver function in chronic diseases like cirrhosis

• Assess response to medications affecting the liver



-------------------------------------------------------------------

🧪 Sample Requirements

》Specimen: Serum

》Tube Type: Plain (red or yellow top)

》Volume: 2–5 mL

》Fasting: Recommended but not essential

》Processing Time: Within 2–4 hours after collection

》Important: Avoid hemolysis for accurate results



-------------------------------------------------------------------

📊 Key Parameters & Reference Ranges

• ALT (SGPT): 7–56 U/L
→ Indicator of liver cell injury

• AST (SGOT): 10–40 U/L
→ Rises in liver, heart, and muscle damage

• ALP: 44–147 U/L
→ Elevated in bile duct obstruction or bone disease

• Total Bilirubin: 0.2–1.2 mg/dL
→ Increased in jaundice and liver dysfunction

• Direct Bilirubin: 0.0–0.3 mg/dL
→ Rises in obstructive jaundice

• Indirect Bilirubin: 0.2–0.9 mg/dL
→ Rises in hemolytic anemia

• Albumin: 3.5–5.0 g/dL
→ Low levels suggest impaired liver synthesis

• A/G Ratio: 1.2–2.0
→ Reversed in advanced liver disease


-------------------------------------------------------------------

🚨 Interpretation of Abnormal Results

🔺 ALT / AST Elevated
→ Hepatitis, drug-induced liver damage, viral infection

🔺 ALP Elevated
→ Bile duct blockage, gallstones, cholestasis

🔺 Bilirubin Elevated
→ Liver dysfunction, hemolysis, hepatic tumors

🔻 Albumin Decreased
→ Cirrhosis, malnutrition, nephrotic syndrome

🔄 Reversed A/G Ratio
→ Suggests chronic or end-stage liver disease


-------------------------------------------------------------------

💡 Important Tips for LFT Handling

● Ensure sample is properly clotted before centrifugation

● Gently handle sample to avoid hemolysis.

● ALT is more specific to liver than AST.

● For suspected biliary obstruction, always correlate ALP with GGT.

RFT/KFT is used to:

• Evaluate kidney health and filtration capacity.

• Detect acute or chronic kidney disease (CKD)

• Monitor hypertension, diabetes, heart failure.

• Assess effects of nephrotoxic drugs.

• Investigate symptoms like swelling, fatigue, decreased urine output.



──────────────────────────

🧪 Sample Requirements

》Specimen: Serum

》Tube: Plain tube (red/yellow top)

》Volume: 2–4 mL

》Fasting: Optional (preferred for consistency)

》Urine sample: May be needed for urea/creatinine ratio or proteinuria

》Processing Time: Within 2–4 hours of collection



──────────────────────────

📊 Key Parameters & Normal Reference Ranges

• Blood Urea: 15–40 mg/dL
→ Measures nitrogenous waste from protein metabolism

• Serum Creatinine:
→ Male: 0.7–1.3 mg/dL
→ Female: 0.6–1.1 mg/dL
→ Indicates glomerular filtration function

• Uric Acid:
→ Male: 3.4–7.0 mg/dL
→ Female: 2.4–6.0 mg/dL
→ Byproduct of purine metabolism; rises in renal dysfunction or gout

• Sodium (Na⁺): 135–145 mmol/L
→ Maintains fluid balance and BP

• Potassium (K⁺): 3.5–5.0 mmol/L
→ Important for muscle and heart function

• Chloride (Cl⁻): 96–106 mmol/L
→ Maintains acid-base balance

• Calcium (optional): 8.5–10.5 mg/dL
→ Affected in advanced renal disease

• BUN/Creatinine Ratio: 10:1 to 20:1
→ Helps differentiate pre-renal vs. renal failure


──────────────────────────

🚨 Interpretation of Abnormal Results

🔺 High Urea & Creatinine
→ Acute Kidney Injury (AKI)
→ Chronic Kidney Disease (CKD)
→ Dehydration
→ Urinary obstruction

🔻 Low Urea/Creatinine
→ Liver dysfunction
→ Malnutrition
→ Overhydration

🔺 High Uric Acid
→ Renal dysfunction
→ Gout
→ Tumor lysis syndrome

🔺 Electrolyte Imbalances
→ High Potassium (Hyperkalemia): Risk of cardiac arrest

Diabetes Diagnosis: The Lab's Role 🔬

Diabetes mellitus is diagnosed and monitored using specific lab tests. These tests are crucial for identifying the condition, assessing its severity, and guiding treatment decisions.

Key Diagnostic Tests: 🩸

•  Fasting Plasma Glucose (FPG): ⏰ Measures blood glucose levels after at least 8 hours of fasting. Diabetes is indicated by a FPG of ≥126 mg/dL (7.0 mmol/L).

•  Hemoglobin A1c (HbA1c): 📈 Reflects average blood glucose levels over the preceding 2-3 months. A HbA1c of ≥6.5% indicates diabetes.
🚫 This test does not require fasting.

•  Oral Glucose Tolerance Test (OGTT):
🥤 Measures blood glucose levels two hours after consuming a standardized glucose drink. Diabetes is indicated by a 2-hour glucose level of ≥200 mg/dL (11.1 mmol/L).
🤰 This test is often used in pregnancy to diagnose gestational diabetes.

•  Random Plasma Glucose (RPG):
🩸 Measures blood glucose at any time of day, without regard to meals. If symptoms of diabetes are present, a RPG of ≥200 mg/dL (11.1 mmol/L) confirms diagnosis.

Important Points to Emphasize: ⚠️

•  Accuracy is Crucial: ✅ Proper sample collection and handling are essential for reliable results.

•  Diagnosis Requires Confirmation:
📝 A single abnormal result should be confirmed with a repeat test on a different day, or by using a different diagnostic test.
•  Clinical Context Matters:
🩺 Lab results should be interpreted in conjunction with the patient's clinical history, physical examination, and other relevant information.
•  Prediabetes is Important Too: 📊 Testing can also show "prediabetes" with A1c levels of 5.7-6.4% or fasting glucose levels of 100 -125 mg/dL. This is a great opportunity for prevention.

🤰 Pregnancy Tests: What the Lab Reveals! 🧪

Pregnancy tests detect human chorionic gonadotropin (hCG), a hormone produced during pregnancy. These tests can be performed on urine or blood samples.

I. Urine Pregnancy Tests: 🚽

•  Sample: Urine (typically first-morning urine, as it's more concentrated).
•  Method: Immunoassay (lateral flow assay). A test strip is dipped into the urine sample. The strip contains antibodies that bind to hCG.
•  How it Works:
  •  If hCG is present, it binds to the antibodies on the test strip, forming a complex.
  •  This complex migrates along the strip and binds to another antibody in the test region, creating a visible line (positive result).
  •  A control line also appears to confirm that the test is working correctly.
•  Advantages:
  •  Easy to use 🏠
  •  Relatively inexpensive 💲
  •  Provides quick results (usually within minutes) ⏱️
•  Limitations:
  •  Less sensitive than blood tests. May give false negatives early in pregnancy.
  •  Can be affected by diluted urine or improper technique.

II. Blood Pregnancy Tests: 🩸

•  Sample: Blood (serum or plasma).
•  Types:
  •  Qualitative hCG: Simply detects the presence or absence of hCG (positive or negative).
  •  Quantitative hCG (Beta-hCG): Measures the exact amount of hCG in the blood.
•  Method: Immunoassay (various methods, including ELISA, chemiluminescence).
•  How it Works: Similar to urine tests, but using antibodies to bind and detect hCG in the blood sample.
•  Advantages:
  •  More sensitive than urine tests ⬆️. Can detect pregnancy earlier (even before a missed period).
  •  Quantitative hCG can provide information about the gestational age of the pregnancy and can be used to monitor the health of the pregnancy.
•  Limitations:
  •  Requires a blood draw 💉
  •  More expensive than urine tests 💸
  •  Takes longer to get results (usually a few hours) ⏳

Clinical Applications: 🩺

•  Confirmation of Pregnancy: Both urine and blood tests are used to confirm pregnancy.
•  Early Pregnancy Detection: Blood tests can detect pregnancy earlier than urine tests.
•  Monitoring High-Risk Pregnancies: Quantitative hCG is used to monitor pregnancies at risk of miscarriage or ectopic pregnancy.
•  Diagnosis of Pregnancy-Related Complications: HCG levels can be useful in diagnosing ectopic pregnancies, molar pregnancies, and other pregnancy-related complications.

Important Note: ❗ Always consult with a healthcare provider for interpretation of pregnancy test results and for appropriate medical care.

🩸 Understanding Anemia: A Compreatology lab is essential for diagnosing and classifying anemias. Accurate diagnosis leads to effective treatment!

I. What is Anemia? 🩸

•   Definition: Deficiency of red blood cells (RBCs) or hemoglobin (Hgb), reducing oxygen delivery.
•   Normal Hemoglobin Value:
    *   Men: 13.5-17.5 g/dL
    *   Women: 12.0-15.5 g/dL
•   Common Causes: Poor diet, low iron, impaired absorption.

II. Classification Based on Morphology: 🔍

•   A. Microcytic Hypochromic: 🔴⬇️ (Small and pale RBCs)
    *   MCV < 80 fL
    *   MCHC < 32 g/dL
•   B. Normocytic Normochromic: 🔴⚪️ (Normal size and color)
    *   MCV 80-100 fL
    *   MCHC 32-36 g/dL
•   C. Macrocytic: 🔴⬆️ (Large RBCs)
    *   MCV > 100 fL
    *   MCHC 32-36 g/dL

III. Microcytic Hypochromic Anemias: 🔴⬇️

•   Definition: Small and pale RBCs due to impaired hemoglobin synthesis.

A. Iron Deficiency Anemia (IDA): 🥄

•   Definition: Insufficient iron for hemoglobin production. 🩸
•   Causes: Poor diet, malabsorption, blood loss.
•   Laboratory Diagnosis:
    *   Low serum iron 🧪
    *   Low serum ferritin 📦 (best indicator)
    *   High TIBC ⛓️
    *   Low transferrin saturation ⚙️
    *   Elevated RDW 📈
    *   Peripheral Blood Film:
        *   Microcytes 🔴⬇️
        *   Hypochromia ⚪️
        *   Anisocytosis (variable size) 📏
        *   Poikilocytosis (variable shape): pencil cells (elongated), target cells (bullseye) 🎯
•   Symptoms: Fatigue, pallor, SOB, headache, dizziness, pica, koilonychia (spoon nails).
•   Treatment: Iron supplements 💊, diet changes 🥗, address underlying cause, IV iron if needed.

B. Thalassemia: 🧬

•   Definition: Inherited disorders with reduced globin chain production (alpha or beta).
•   Types: Alpha thalassemia, beta thalassemia.
•   Laboratory Diagnosis:
    *   CBC: Microcytic hypochromic anemia.
    *   Peripheral Blood Film:
        *   Microcytes 🔴⬇️
        *   Hypochromia ⚪️
        *   Target cells 🎯
        *   Basophilic stippling (blue dots)🔵
        *   Anisocytosis
        *   Poikilocytosis.
    *   Hemoglobin electrophoresis: Detects abnormal Hb.
•   Symptoms: Variable severity.
•   Treatment: Mild cases – none. Severe cases – transfusions, chelation, BMT.

C. Anemia of Chronic Disease (ACD): 🦠

•   Definition: Anemia related to chronic inflammation. 🔥
•   Causes: Chronic infections, autoimmune diseases, cancer.
•   Laboratory Diagnosis:
    *   May start as normocytic, can become microcytic.
    *   Serum iron: Low or normal.
    *   TIBC: Low or normal.
    *   Ferritin: Normal or high.
    *   Peripheral Blood Film: Usually normocytic/normochromic; can be microcytic/hypochromic.
•   Symptoms: Fatigue, weakness related to the underlying condition.
•   Treatment: Treat the underlying chronic disease.

D. Sideroblastic Anemia (SBA): ⚙️

•   Definition: Impaired iron incorporation into hemoglobin; iron accumulates.
•   Causes: Inherited or acquired.
•   Laboratory Diagnosis:
    *   CBC: Microcytic or macrocytic.
    *   Bone marrow smear: Ringed sideroblasts (Prussian blue stain).🔵
    *   Peripheral Blood Film:
        *   Dimorphic population (both small and large RBCs)
        *   Basophilic stippling
        *   Pappenheimer bodies (iron inclusions)
•   Symptoms: Weakness, fatigue, splenomegaly.
•   Treatment: Vitamin B6, blood transfusions, iron chelation.
