Where: 
• E = Efficiency of primer and probe set. This efficiency is calculated with the formula 
(% Efficiency * 0.01) + 1, where 100% efficiency = 2

• GOI = Gene of interest (one target)
Standard Deviation of Relative Quantity
The standard deviation of the relative quantity is calculated with the following formula:
Where:
• SD Relative Quantity = standard deviation of the relative quantity
•SD C
q
 sample = Standard deviation of the C
q
 for the sample (GOI)
• Relative Quantity = Relative quantity of the sample
• E = Efficiency of primer and probe set. This efficiency is calculated with the formula 
(% Efficiency * 0.01) + 1, where 100% efficiency = 2
• GOI = Gene of interest (one target)
Efficiency Corrected Cq (Cq
E
)
The efficiency corrected Cq is calculated by the following formula:
Where:
• E = Efficiency
Mean Efficiency Corrected Cq (MCq
E
)
The mean efficiency corrected Cq is calculated with the following formula:
Where:
•Cq
