Assay is typically calculated as the percentage of the active ingredient present in a sample compared to the total sample weight. Potency is a measure of the strength or concentration of the active ingredient in a sample relative to a standard reference. The formula for assay and potency calculations may vary depending on the specific assay method and the properties of the substance being analyzed.

How do you assay thrombin potency?
You can assay thrombin potency by measuring its ability to convert fibrinogen to fibrin, typically using a chromogenic or clot-based assay. The results are compared to a standard curve to determine the potency of the thrombin sample.
What is the formula to calculare the percent recovery in assay or related substance?
The formula to calculate the percent recovery in an assay or related substance is: [ \text{Percent recovery} = \left( \frac{\text{Amount detected}}{\text{Amount spiked}} \right) \times 100% ] This formula helps to determine the efficiency of the assay in detecting the target substance by comparing the measured amount to the known amount added.
What is the difference between assay on as is basis and assay on anhydrous basis?
Assay on as is basis refers to the percentage of a substance in its current state, including any impurities or water content present. Assay on anhydrous basis, on the other hand, refers to the percentage of a substance calculated without including any water content present. This difference is important when comparing the purity of substances or calculating accurate concentrations in chemical analysis.
Formula for calculating mass?
The formula for calculating mass is mass = density x volume. This formula relates the mass of an object to its density (amount of matter in a given volume) and volume (amount of space an object occupies).
What is the difference between assay and analysis?
Assay is the quantitative determination of the amount of a component in a sample. Purity is the determination of the impurities in the sample. It can be quantitative, semi-quantitative or qualitative. For example : if you dissolve 4 grams of compound A (with no impurities in it) in 6 grams of water, you get a solution of compound A with 100% purity and 40% assay. From the ICH Guideline Q2A (Validation of Analytical methods) : "- Testing for impurities can be either a quantitative test or a limit test for the impurity in a sample. Either test is intended to accurately reflect the purity characteristics of the sample. [...] - Assay procedures are intended to measure the analyte present in a given sample. In the context of this document, the assay represents a quantitative measurement of the major component(s) in the drug substance."

What is the difference between potency and assay?
Potency is the purity of the compound ;this states % available of the main component without water and residual solvents Assay is defined as Potency plus water and residual solvents and other remaining fractions please note assay can also be expressed as as is basis or dry basis Assay and Potency are same if assay is exprtessed as as is basis please note Potency word is mainly used for Antibiotics and bilogicals courtsey ; CDER , USFDA ; Dr.Uttam Krishna
What is a four point biological assay?
