Validation Responsibilities

The Validation Team has overall responsibility for validating the facility. The Quality Assurance Manager has responsibility for approval of all validation protocols, final reports, standard operating procedures, chemical and microbiological testing, as well as other critical cGMP documentation.

When running SCREEN for a point source, or for flare releases and area sources discussed below, you are first asked to provide a one line title (up to 79 characters) that will appear on the output file. You will then be asked to identify the source type, and should enter P or p for a point source (the model will identify either upper or lowercase letters and will repeat the prompt until a valid response is given). For a point source, you will be asked to provide the following inputs ... 

Some GLP professionals consider positive control substances (i.e., those materials intended to validate responsiveness of the test system to a chemical or biological challenge) to also be reference substances, as opposed to control substances however, the point is somewhat moot as the FIFRA GLP Standards characterization and handling requirements are exactly the same for both control and reference substances. As with test and control substances, reference substances must be characterized (usually determination of purity and stability) according to the abbreviated GLP Standards (see next section). 

If the method for acquiring a VALUE is ASKIT, then a user PROMPT is stored. In order to guarantee a valid response to the question, a LISP function to check the answer is included with the FACT. Table I lists the currently implemented response checking functions. Whenever the inference engine reaches one of these facts, searching is stopped and the user is prompted for a value. 

Figure 7 shows part of the user consultation that elicited the inputs listed in Figure 6. The current user interface provides on-line help as well as a menu of numbered valid responses. The user may either type in the number or the listed item. In answer to the user typing " ", the system rephrases the question, redisplays acceptable values, and specifies what other characters are recognized. If this is not enough information, the...

This, of course, is a very important part of the program. We are developing it on an as-needed basis in response to feedback from users. In particular, we still have not implemented a complete explanation facility. The user interface currently provides online help and a menu based selection of valid responses whenever applicable. 

Working with the contract manufacturer, the validation responsibilities must be clearly delineated. A clear understanding of these responsibilities will minimize the confusion, save precious time, and help assure that the preapproval inspection will be successful.

Victims have been followed up periodically by St. Luke s International Hospital. A survey was conducted on 660 victims one year after the attack, and valid responses were obtained from 303 victims (Ishimatsu et al, 1996). The results revealed that 45% still had some symptoms. Regarding physical symptoms, 18.5% of the victims still complained of eye problems, 11.9% of easy fatigability, and 8.6% of headache. As for psychological symptoms, 12.9% complained of fear of subways while, 11.6% indicated fears concerning the escape from the attack. Another survey was conducted three years after the attack, and 88% of the respondents still complained of some aftereffects (Okumura etal., 1999). However, these studies lack objectivity victims with after-effects tended to respond more often and there were limits in eliminating biases. 

Report the presence but not concentration of the analogue. While this is a valid response, it is likely to directly lead to questions about the significance of the levels. 

Table 14.7 shows the scaled and centred coefficients for all valid responses. The values display the physical effect on the appropriate particle property, when the factor is raised for one level. 

By proceeding this way, it is very probable that the result of the integration of the chromatographic peak will be compatible with the use of the validated response function. Proceeding in this manner is legitimate only if one has previously performed tests during method validation to verify that dilution of the sample does not alter the result of the dosage.
