Kidney Function Tests in Biochemistry: Interpretation and Indications Quiz

Renal Function Tests

• The formula to calculate 24-hour creatinine clearance is: Urine creatinine (mg/24hr) / Serum creatinine (mg/dL) x 1440 (min) / Body weight (kg) x 100.

Serum Creatinine Levels

• The normal range for serum creatinine levels is 0.5-1.1 mg/dL.

Serum Uric Acid Levels

• The clinical significance of measuring serum uric acid levels is to assess renal function and detect abnormalities.
• The normal range for serum uric acid levels is 3.5-7.2 mg/dL.

Renal Damage

• The earliest sign of renal damage is a decrease in glomerular filtration rate (GFR).

Renal Function Tests

• The primary indicator of kidney health is creatinine clearance.
• Electrolyte panel is not a renal function test.

Indications for Kidney Function Tests

• There is no indication for performing kidney function tests in healthy individuals with no risk factors.

Creatinine Removal

• Creatinine is removed from the body through glomerular filtration.

Glomerular Filtration Rate (GFR)

• A decrease in GFR indicates renal impairment or kidney damage.

Factors Affecting GFR

• Factors that can cause a decrease in GFR besides renal impairment include: age, sex, muscle mass, and some medications.

Test your knowledge on interpreting various kidney function tests and understanding the indications for Kidney Function Tests (KFT) in the field of biochemistry. Learn about assessing kidney damage, monitoring effects of renal toxic drugs, and tracking the progression of renal damage.
