What are three phases of laboratory testing?

The three phases of laboratory testing are pre-analytical phase, analytical phase, and post-analytical phase. The pre-analytical phase refers to all the steps taken prior to the actual testing of a specimen (e.g. specimen collection, transport, accessioning). The analytica phase includes the actual testing analysis. The post-analystical phase includes test reporting and interpretation.


If the cost of fixing a defect in the requirements phase is 1 what is the relative cost of fixing a defect in the Testing Phase?

It is safe to estimate that the cost of fixing a problem increases by roughly an order of magnitude in each phase of development.requirements phase (cost 1)preliminary design phase (cost 10)detailed design phase (cost 100)coding phase (cost 1000)testing phase (cost 10000)So as an estimate if a problem is not found until test phase it will cost roughly 10000 times as much to fix as it would if the problem had been found in the requirements phase.

What is PH2?

PH2 refers to the second phase of a clinical trial, where the safety and effectiveness of a drug is further evaluated in a larger group of patients. It follows Phase 1 (safety testing on a small group) and precedes Phase 3 (more extensive testing on a larger group).


What is phase 2 testing?

Phase 2 testing is a crucial stage in clinical trials that evaluates the efficacy and side effects of a drug or treatment in a larger group of participants, typically ranging from 100 to 300 individuals. This phase aims to determine whether the treatment is effective for a specific condition and to further assess its safety profile. It follows successful Phase 1 trials, which primarily focus on safety and dosage. Phase 2 results help inform the decision to advance to Phase 3 trials, where the treatment is tested in a larger population.
