After extraction, all specimen containers must be labeled with at least two of the following identifiers (at the time of collection): patient's name, date of birth, hospital number, test request form number, accession number, or a unique random number. All specimens should be labeled with the patient present.
The headquarters are in Frome Road, Adelaide, and it has many patient collection centres and numerous laboratories located throughout South Australia. The Hanson Centre for Cancer Research was established in 1991 by SA Pathology, broadening its scope of research and becoming the Hanson Institute in 2001.
Also biobanks, which do specimen storage, cannot take full responsibility for specimen integrity, because before they take custody of samples someone must collect and process them and effects such as RNA degradation are more likely to occur from delayed sample processing than inadequate storage.
Gross examination of a kidney (right of image) with a renal oncocytoma (left of image).. Gross processing, "grossing" or "gross pathology" is the process by which pathology specimens undergo examination with the bare eye to obtain diagnostic information, as well as cutting and tissue sampling in order to prepare material for subsequent microscopic examination.
For example, the ColoGuard test may be used to screen people over 55 years old for colorectal cancer. [57] Cancer is a longtime-scale disease with various progression steps, molecular diagnostics tools can be used for prognosis of cancer progression. For example, the OncoType Dx test by Genomic Health can estimate risk of breast cancer.
For example, a common application of cytopathology is the Pap smear, a screening tool used to detect precancerous cervical lesions that may lead to cervical cancer. Cytopathologic tests are sometimes called smear tests because the samples may be smeared across a glass microscope slide [ 4 ] for subsequent staining and microscopic examination.
The FDA requires nonclinical laboratory studies on new drugs, food additives, and chemicals to assess their safety and potential effectiveness in humans in compliance with 21 CFR Part 58, Good Laboratory Practice for Nonclinical Studies under the Federal Food Drug and Cosmetic Act and Public Health Service Act.

A typical method of sample acceptance (in a clinical chemistry lab) is as follows: Sample is received. Sample is checked (to ensure that the sample is sent in the correct container for the specimen). Patient's details checked and matched on both form and sample (non-matching samples and/or forms rejected).
