Q

What are the limitations of creatinine?

A

Inaccurate with mild renal impairment

  • reduced in low muscle
  • increase with high protein diet
  • affected by certain drugs

Q

What is Cystatin C?

A
  • Low molecular wt produced by all nucleated cells
  • Not affected by diet, gender, age, muscle mass
  • affected by steroids
17
Q

What is creatinine clearance good for?

A

Urine collections unreliable

  • overestimates GFR
  • Drug influences creatinine assays
18
Q

What is the Cockroft-Gault formula?

A

140-agewt/72Scr

  • avoids urine collection
  • Overestimates for obesity and low protein diet
  • better than plasma creatinine for renal impairment
19
Q

What is MDRD?

A

Modification of Diet in Renal Dz

- 186Scrage0.742 (Females) 1.210

20
Q

What is CDK-EPI?

A

included age, sex, race and serum creatinine

- 60mL/min/1.73m^2

21
Q

What is the best approximation of true GRF?

A

Plasma clearance

  • invasive
  • use radioisotopes
22
Q

What is the management of CKD?

A
  1. Treatment of reversible causes of renal dysfunction
  2. Preventing or slowing progression of renal dz
  3. Treatment of complication of renal dysfunction
  4. Preparation and initiation of renal replacement therapy
