Question 2. Gastric function tests
Answer:

Question 3. Liver function tests
Answer:

Uses:

• Assess the capacity of the liver to function
• Detects abnormalities and extent of damage

Tests:

Question 4. Creatinine clearance value
Answer:

• Creatinine is an excretory product derived from creatine phosphate

Definition:

• It is defined as the volume of plasma that would completely clear of creatinine per min

Calculation:

• Creatinine content of 24-hour urine is collected
  • Plasma concentration is estimated

\(C=\frac{U^* V}{P}\)

U = creatinine concentration in urine (mg/ml)

V = urine excreted per min in ml

P = creatinine concentration in plasma (mg/ml)

Normal value:

• Its value is close to GFR and is sensitive
• Normal range is 120-145 ml/min

Significance:

• Used for early detection of kidney impairment
• A value below 75% of normal -indicates decreased GFR, renal damage
