Enter the total TCH level and the total creatinine level into the Calculator. The calculator will evaluate the Thc Creatinine Ratio. 

Thc Creatinine Ratio Formula

THCC  = THC / C

Variables:

  • THCC is the Thc Creatinine Ratio ()
  • THC is the total TCH level
  • C is the total creatinine level

To calculate Thc Creatinine Ratio, divide the THC level by the total creatinine level.

How to Calculate Thc Creatinine Ratio?

The following steps outline how to calculate the Thc Creatinine Ratio.


  1. First, determine the total TCH level. 
  2. Next, determine the total creatinine level. 
  3. Next, gather the formula from above = THCC = THC / C.
  4. Finally, calculate the Thc Creatinine 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.

total TCH level = 388

total creatinine level = 128

FAQs

What is the significance of the THC to Creatinine Ratio?

The THC to Creatinine Ratio is used to assess the concentration of THC in the urine, adjusting for urine concentration. A higher ratio may indicate recent cannabis use, while a lower ratio could suggest past use or passive exposure.

How can THC levels vary in individuals?

THC levels can vary based on several factors including the frequency of cannabis use, the potency of the cannabis, individual metabolism rates, and the time since last use.

Why is creatinine used in this calculation?

Creatinine is a waste product produced by muscles and filtered out of the blood by the kidneys. Because its production and clearance are relatively constant in an individual, it is used as a benchmark to adjust for urine concentration in drug testing.

Can the THC to Creatinine Ratio be used to determine exact time of cannabis use?

No, the THC to Creatinine Ratio cannot precisely determine the exact time of cannabis use due to variability in individual metabolism, THC dose, and frequency of use. It can, however, provide an estimate of recent versus past use.
