Enter the immature neutrophil and the total neutrophil into the IT Ratio Calculator. The calculator will evaluate the IT Ratio. This calculator can also evaluate the immature or total nuetrophil given the other variables.

IT Ratio Formula

The following two example problems outline the steps and information needed to calculate the IT Ratio.



  • ITR is the IT Ratio ( )
  • IN is the immature neutrophil 
  • TN is the total neutrophil 

To calculate IT Ratio, divide the amount of immature neutrophil by the total neutrophil.

How to Calculate IT Ratio?

The following steps outline how to calculate the IT Ratio.

  1. First, determine the immature neutrophil. 
  2. Next, determine the total neutrophil. 
  3. Next, gather the formula from above = ITR = IN / TN.
  4. Finally, calculate the IT Ratio.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

immature neutrophil = 30

total neutrophil = 100

ITR = IN / TN = ?
