Laboratory identification number

Biology Retrieval Subsystem. The biology retrieval subsystem consists of two indexed sequential files containing biological test data relating to the structures of the chemistry subsystem. There are over three million records occupying 6 disk packs of 37 million characters each. Both files are sequenced by sample number (BN) and laboratory identification number (Lab I.D.). The data fields are dependent on the type of experimentation done by a specified laboratory and are predefined in a data neune dictionary. From a user s point of view the two files... 

Specific information on the handling of the processed fractions may also be included. Specific containers or types of containers may be required to minimize analytical interference. Sample identification numbers may be assigned in the protocol or may be generated by the processing facility. In either case, each processed fraction should have a unique identification number to reduce confusion at the processing facility and at the analytical laboratory where the residues will be determined. 

Record keeping carried out not only by the analyst in laboratory notebooks, but also in logbooks for each instrument. After completion, these should be archived for at least ten years. Records should include the type of sample (with a unique identification number), collection method, location, date, description of sample, preparation and analysis method, and instrumental conditions, original data files, and the name of the person responsible. 

A sample tracking module, using a unique computer-generated identification number, that allows sample tracking from the time the sample enters the laboratory until it is analyzed. 

Each collected sample must have its own unique identification number. The project staff will use this number to track the sample in the field and at the home office during the project assessment phase. The laboratory will use this number for matching the sample and the requested analysis. The laboratory will enter the field sample IDs into the data base and assign the samples with laboratory IDs for internal tracking. Analytical results will be reported for the samples identified according to their field and laboratory IDs. 

The original analytical data submitted by Member States to the OPCW Laboratory are archived. The original analytical data is assigned unique OPCW codes at the OPCW Laboratory before archiving. This code comprises the identification number of the laboratory that contributed data, a number that corresponds to the type of analytical technique, a number corresponding to the data entry into the OCAD, and letters that distinguish vapor phase IR (v) from condensed phase and other types of IR spectra, diastereoisomers (a, b, c, etc.) and resubmitted data (r, s, t, etc.) (see Figure 3). 

In many laboratory information systems, electronic entry either in the laboratory or at a nursing station of a test order for a uniquely identified patient generates a specimen label bearing a unique laboratory accession number. A record is established that remains incomplete until a result (or set of results) is entered into the computer against the accession number. The unique label is affixed to the specimen collection container when the blood is drawn. Proper alignment of the label on the collection container is critical for subsequent specimen processing when using bar coded labels. Arrival of the specimen in the laboratory is recorded by a manual or computerized log-in procedure. In other systems, the specimen is labeled at the patient s bedside with the patient identification and collection information and enters... 

The simplest identification of specimens for laboratory purposes has proved to be a serial number allocated to them in order of their arrival. The chances of error are reduced if the number of times the identification number has to be written are kept to a minimum, and this can be achieved by having available at the reception desk a reel of perforated gummed paper from which may be torn an appropriate number (e.g., six) of small labels for each new specimen, these labels all having the same number. Labels are stuck immediately on the request form and the specimen container, both of which can then pursue their separate paths through the laboratory, simply and unequivocally identified (W4). The spare labels accompany the specimen and can be used whenever some of it is transferred to a fresh container, or for numbering a bench work sheet. 

The specimen is received into the laboratory along with a completed requisition indicating the specimen identification, number of cassettes, researcher name, department, account, telephone extension, procedures to be performed on the specimen, and any additional pertinent information. The requisition is logged into the proper log book (research or patient) and given a laboratory number for identification. Then the cassettes are placed on the automatic processor (overnight or day run) to be dehydrated, cleared, and infiltrated with paraffin see Table 2). When the processor has finished, the cassettes are removed and placed in a paraffin bath to await embedding. The specimen is... 

The laboratory must observe and document the conditions that exist at the time of receipt and that may adversely impact on the integrity of a sample. Irregularities such as unsealed sample containers on receipt, samples without any identification code, mismatches between the sample number and the sample identification number on the form, inadequate sample volume/weight, unusual condition of the sample (e.g., color, odor, or hemolysis) should be noted. Instructions from competent authorities and/or clients may be required to decide whether the sample should be rejected, and in any case the abnormalities should be documented in the sample logbook for possible future reference.

A validation report that describes overall conduct of the validation, and includes all of the relevant tables needed to support the interpretation of results and final conclusions, should be written prior to initiating sample analysis. The report should be assigned a unique identification number that can be used as a reference in the sample analytical report. A cover page should contain, at a minimum, the name and address of the laboratory and the report and amendment number (if applicable). A signature page that includes, at a minimum, the author(s), reviewer(s) and laboratory management should also be included. 

Another aspect of LIMSs is their flexibility and ability of configuration, This means that the LIMS functions and the user interface can be adapted to the requirements of the laboratory. Such flexibility is necessary because tasks can change and new demands can arise. Mainly new definitions, fields, algorithms, screen layouts, and reports then have to be created, but sometimes it occurs that the structure of the data or keys (identification numbers) must be changed. This is a serious intervention in a LIMS and should not be done, or only seldom. 

Although a number of solid compounds of plutonium were synthesized by ultramicrochemical techniques during our first year and a half at the Metallurgical Laboratory, it was not until November, 1943 that a positive identification of a crystal structure was made. W. H. Zachariasen joined the project in the fall of 1943 and very soon began to make definitive identifi-...
