INULINE CLEARANCE

NOTHING OF THIS SHOULD BE OMMITED

Plasma Clearances• Renal clearance of a substance is the volume of plasma that is completely cleared of the that substance by the kidneys per unit Time.

• However this definition is quite abstract because there is no volume of plasma that is cleared COMPLETELY!

• (Basic formula is  C=U X V/P (Put “s” with all except “V”)

Cs = Us X V/ PsCs X Ps = Us X V

Cs = Rate at which  Plasma that is cleared of a substance each min (ml / Min)Us = Conc. of Substance  In Urine (mg / ml)Ps = Plasma Conc. Of substance (mg / ml)V = Urine Flow Rate  (ml / Min)

Inulin  Clearance

If a substance is freely filtered (filtered as freely as water or Glucose) but is not reabsorbed or secreted by the renal tubules, Than its clearance rate would be equal to GFR-As per formula(I) Ci = Ui X V   = GFR     OR  Ci X Pi = Ui X V = GFR X Pi (Filtered Load)                   Pi                                       OR    (II) Clearance rate will be equal to GFR & Its rate of excretion in Urine 

                                      Ci X Pi = GFR X Pi = Ci = GFR = Ui X V                                        OR(III) Clearance value will be equal to filtered Load

                                    Ci X Pi = GFR X Pi (Filtered Load)

Inulin  Clearance & GFR

Inulin is the substance that is filtered completely in Glomerulus & it is neither secreted nor reabsorbed in tubules.

Other substances that have been used  clinically to estimate GFR include radioactive iothalamate and Creatinin.

Please remember that Ci is Clearance Rate & is = Ui X V / Pi

While Ci X Pi is Clearance Value & is = Ui X V

Value & importance of both are same in normal conditions.

Calculation for InulinSince  Pi is 1 & V is 1 under normal conditions so GFR = Ui = Ci

Please note that-if Inulin was 1mg / ml in Plasma & was Completely filtered than its Conc. in Urine would be 125mg  /ml because GFR is125/ 

ml/Min. It was not re-absorbed at all. At this GFR Urine flow is 1 ml / Minute

So Here- Ci = GFR     & Since Ci = Ui X V / Pi so 

GFR would also Be the same I.E. GFR = Ui X V / Pi  OR    GFR X Pi (FL) = Ci X Pi = Ui X V / Pi     (I.E. FL = Clearance value)

I.E. -GFR  X Pi (125 X 1) = Cinulin  X Pi (125 X 1) = Ui X V (125 X 1)

 Or GFR = Ci = 125ml (Ui) X 1ml / Min (V) / 1mg / ml (Pi) = 125ml / Min

Estimation of GFR BY Inulin clearance

Please note that same is the formula for Cs so Ci = Ui X V/Pi= GFR

OR

Cin = 125 X1 / 1 = 125ml / Min = GFR
