What is method development and validation?

Analytical method development and validation are continuous and interconnected activities conducted throughout the drug development process. The practice of validation verifies that a given method measures a parameter as intended and establishes the performance limits of the measurement.

What is assay development and validation?

The purpose of assay development and validation is to find a suitable method applicable to a chosen analyte in a specific biological matrix. The analysis outcome might be inaccurate if the assay is not validated correctly and deemed unreliable.

What is bioassay procedure?

a. Bioassays are procedures which estimate the amount of radioactive material deposited in the body, either by direct measurement, using sensitive x-ray detectors placed over the chest (lung counting) and/ or other organs, or by detection of radioactivity in the excreta (feces and urine).

What are the steps in analytical method validation?

Identify the purpose

  1. Select the method used.
  2. Identify the method steps.
  3. Determine product specification limits.
  4. Perform a risk assessment.
  5. Characterize the method.
  6. Complete method validation and transfer.
  7. Define the control strategy.
  8. Train all analysts.

What is the purpose of method validation?

Method validation is the process used to confirm that the analytical procedure employed for a specific test is suitable for its intended use. Results from method validation can be used to judge the quality, reliability and consistency of analytical results; it is an integral part of any good analytical practice.

What is validation method?

Method validation is a procedure of performing numerous assessments designed to verify that an analytical test system is suitable for its intended reason and is capable of providing beneficial and legitimate analytical data [4, 5, 6, 7, 8].

What are different types of assays?


  • Immunoassays (IAs): — Enzyme immunoassays (EIAs) — Chemiluminescent immunoassays (CLIAs) — Haemagglutination (HA)/particle agglutination (PA) assays. — Rapid/simple single-use assays (rapid tests)
  • Nucleic acid amplification technology (NAT) assays.

Is an example of bioassay?

One well known example of a bioassay is the “canary in the coal mine” experiment. To provide advance warning of dangerous levels of methane in the air, miners would take methane-sensitive canaries into coal mines. If the canary died due to a build-up of methane, the miners would leave the area as quickly as possible.

What are the different methods of validation?

According to ICH Guidelines, the following four types of methods require validation:

  • Identification tests.
  • Quantitative tests for impurities content.
  • Limit tests for the control of impurities.
