True or False: The minimum time to fix tissue samples suspected of CJD is one week.

The statement that the minimum time to fix tissue samples suspected of Creutzfeldt-Jakob Disease (CJD) is one week is accurate. CJD is a transmissible spongiform encephalopathy caused by prions, which are highly resistant to standard decontamination methods.

Proper fixation helps in preserving the tissue and assists in the most reliable pathological examination. Typically, a fixation period of at least one week at a suitable fixation solution, such as formalin, is recommended for thorough penetration and fixation of the tissue. This is important not only for diagnostic purposes but also to help mitigate the potential risk of transmitting prion diseases through tissue handling.

Understanding the nature of CJD and the required time for effective fixation provides critical information for laboratory safety protocols and ensures that samples are handled appropriately to prevent any risk of prion transmission.
