Chemical Product Testing
Our testing solutions ensure the practical implementation of REACH requirements in concert with any additional developmental and reproductive toxicity testing requirements depending on tonnage per annum (TPA) marketed.
INFORMATION REQUIREMENTS AT 10 TPA:
Where there are no concerns over reproduction or development, REACH calls for starting with the screening study (OECD421/422) at this tonnage.
Where there are serious concerns about the potential for adverse effects on fertility or development, either a prenatal developmental toxicity study or a two-generation or extended one-generation reproductive toxicity study may be proposed instead of the screening study.
INFORMATION REQUIREMENTS AT 100 TPA
REACH requires a prenatal developmental toxicity study in one species (usually rat). If the 28-day or 90-day study indicates adverse effects on reproductive organs or tissues, a two-generation or extended one-generation reproductive toxicity study in one species should be conducted.
INFORMATION REQUIREMENTS AT 1000 TPA
REACH requires a prenatal developmental toxicity study in one species (usually rat). The need for a second species is judged on a case-by-case basis. A two-generation or extended one-generation reproductive toxicity study in one species is also called for and the need for a second species is judged on a case-by-case basis.

PK/PD and Metabolism
During the drug discovery process, ADME (absorption, distribution, metabolism, and excretion) and PK studies are deemed necessary to evaluate bioavailability.
Inhalation
Inhalation toxicity studies are required to assess the exposure hazards of consumer products or to manufacturing workers.
General Toxicology
Our team of experienced, highly-educated scientists, experts in toxicology, molecular biology, chemistry and immunology, fully understands that the drug development process is distinct for each approach.
Safety Pharmacology
Safety pharmacology satisfies a key requirement in the drug development process, assessing any potential adverse effects that drug candidates may have on the body’s major physiological systems
