If you have an account with us, please log in.A medical laboratory or clinical laboratory is a laboratory where clinical pathology tests are carried out on clinical specimens to obtain information about the health of a patient to aid in diagnosis, treatment, and prevention of disease. Medical laboratories vary in size and complexity and so offer a variety of testing services.

Commercial medical laboratories operate as independent businesses and provide testing that is otherwise not provided in other settings due to low test volume or complexity. In hospitals and other patient-care settings, laboratory medicine is provided by the Department of Pathology, and generally divided into two sections, each of which will be subdivided into multiple specialty areas. Layouts of clinical laboratories in health institutions vary greatly from one facility to another.

For instance, some health facilities have a single laboratory for the microbiology section, while others have a separate lab for each specialty area. The United States has a documented shortage of working laboratory professionals. The decline is primarily due to retirements, and to at-capacity educational programs that cannot expand and that limit the number of new graduates. Professional organizations and some state educational systems are responding by developing ways to promote the lab professions in an effort to combat this shortage.

In most developed countries, there are two main types of lab processing the majority of medical specimens. Hospital laboratories are attached to a hospitaland perform tests on their patients.

Private or community laboratories receive samples from general practitionersinsurance companies, clinical research sites and other health clinics for analysis. For extremely specialised tests, samples may go to a research laboratory. Some tests involve specimens sent between different labs for uncommon tests. For example, in some cases it may be more cost effective if a particular laboratory specializes in a less common tests, receiving specimens and payment from other labs, while sending other specimens to other labs for those tests they do not perform.

In many countries there are specialized types of Medical Laboratories according to the types of investigations carried out. Organisations that provide blood products for transfusion to hospitals, such as The Red Cross, will provide access to their reference laboratory for their customers. Some laboratories specialize in Molecular diagnostic and cytogenetic testing, in order to provide information regarding diagnosis and treatment of genetic or cancer-related disorders.

In a hospital setting, sample processing will usually start with a set of samples arriving with a test request, either on a form or electronically via the laboratory information system LIS. Inpatient specimens will already be labeled with patient and testing information provided by the LIS.

Entry of test requests onto the LIS system involves typing or scanning where barcodes are used in the laboratory number, and entering the patient identification, as well as any tests requested. This allows laboratory analyzers, computers and staff to recognize what tests are pending, and also gives a location such as a hospital department, doctor or other customer for results reporting.

Once the specimens are assigned a laboratory number by the LIS, a sticker is typically printed that can be placed on the tubes or specimen containers.

This label has a barcode that can be scanned by automated analyzers and test requests uploaded to the analyzer from the LIS. Specimens are prepared for analysis in various ways. For example, chemistry samples are usually centrifuged and the serum or plasma is separated and tested.

If the specimen needs to go on more than one analyzer, it can be divided into separate tubes.Wellness 2 Essential Blood Test Panel. Thyroid 1 Baseline Blood Test Panel.

The antibodies detected by this test indicate that a person had an immune response to SARS-CoV-2, whether symptoms developed from infection or the infection was asymptomatic. Antibody test results are important in detecting infections with few or no symptoms.

Researchers are currently working to develop the basic parameters for the test, which will be refined as more samples become available.
