Why is specimen handling so important?

It is a foundational principle for any laboratory test procedure that the value of the test is compromised or even negated by using specimens that have not been properly collected, labelled, handled or stored prior to and during the testing process.

Why is proper specimen collection important in laboratory analysis?

The accuracy of these results leads to accurate diagnostic and therapeutic decisions. To ensure maximum accuracy of results proper patient preparation, specimen collection and handling are necessary. This requires the timely provision of properly collected specimens to the laboratory.

How do you handle a specimen in a lab?

When handling specimens, universal safety precautions should always be employed. Appropriate protective clothing and personal protective items should be worn. No tissue, even fixed material, should ever be handled with bare hands. It must be kept in mind that noxious agents are present in the laboratory.

What is the first thing you always do and specimen handling for safety?

1. Always wear gloves and any other indicated barrier protection when collecting and handling laboratory specimens.

Why specimen for microbiology culture should be properly handled?

Specimens for culture MUST be collected properly prior to the initiation of antibiotic therapy to insure optimal conditions for the recovery of pathogens. The laboratory will identify isolates and perform antibiotic susceptibility testing where appropriate.

How do you store specimens?

Specimen storage To increase the sensitivity of diagnostic testing all specimens should be stored frozen (optimally at -70oC) and shipped on dry ice with the exception of fixed tissues and specimens collected in a glass tube (whole blood, whole blood EDTA, whole blood Heparin, serum separating tubes, CPT tubes, etc).

What is specimen collection and handling?

Proper specimen collection and handling is an integral part of obtaining a valid and timely laboratory test result. Specimens must be obtained in the proper tubes or containers, correctly labeled, and then promptly transported to the laboratory.

Why must a specimen be wrapped separately?

Storage and shipping of dried blood spots Each dried filter paper should be wrapped individually in paper, foil or plastic to prevent possible cross-contamination.

What is the importance of following the proper steps in collecting samples?

Collecting samples properly adds to the accuracy of the results. It’s important to plan for testing in order to have the appropriate bottles and supplies on hand to collect and return the samples to the lab.

What is most important about correct blood handling?

The proper handling of blood samples is critical to the outcome of the HAPO Study. Deviations from HAPO protocol and procedures can significantly affect the parameter being measured. It is particularly important that time deadlines and transport conditions be strictly adhered to.

How do you handle specimens in the operating room?

Specimens should be handled as little as possible in order to maintain the integrity of the sample. Action must be taken to prevent drying out of specimens. This may include putting the lid on the specimen container (if the retrieved tissue is to be sent fresh) as soon as it is received from the scrub practitioner.

How are specimens labeled properly?

To maintain patient safety standards, specimens must be properly labeled with the name of the patient, a numerical identifier that is unique to the patient (like DOB or SSN), collection date, and the source of the specimen, where applicable.

How are blood samples handled and stored while being transported?

ALL blood and other potentially infectious material are treated as if they are known to be infectious with HIV or hepatitis and other bloodborne pathogens. All specimens must be transported in a sealed biohazard bag.

How do you preserve a specimen in a biology lab?

Storage advice for preserved biological specimens: Store specimens in screw capped containers that are non-reactive to the storage fluid. The seal should prevent evaporation of the storage solution, and metal lids should be avoided as they may corrode and eventually leak. Use Parafilm to provide an additional seal.

What is the goal of specimen preservation storage and transport of specimen to the laboratory?

Transport all specimens to the laboratory promptly to ensure the survival and isolation of fastidious organisms and to prevent overgrowth by more hardy bacteria. This will provide a more accurate diagnosis of the infectious-disease process. 2.

Do you refrigerate wound cultures?

Pus, tissue, or other material properly obtained from an abscess, biopsy, aspirate, drainage, exudate, lesion, or wound. To ensure proper growth of organisms, place swabs/specimen in anaerobic transporter. Do not refrigerate.

What is the purpose of chilling a specimen?

What is the purpose of chilling a specimen? Chilling a specimen slows down metabolic processes and keeps analytes stable during transport and handling.

What are the different safety precautions during venipuncture?

One of the simplest, yet most important, safety precautions that the phlebotomist uses is gloves. Gloves provide protection against inadvertent contact with a patient’s blood. Almost as important as wearing gloves is disposing of them.

How would you handle a blood draw on an unconscious patient?

The Sleeping or Unconscious Patient: If the patient is sleeping, the phlebotomist should gently wake the sleeping patient and then allow the patient a few minutes to orient himself or herself before beginning the identification process.

What is the purpose of collecting samples?

Sampling is a tool that is used to indicate how much data to collect and how often it should be collected. This tool defines the samples to take in order to quantify a system, process, issue, or problem.

How do you store a histology specimen?

Routine Pathology specimens should be submitted in an appropriately-sized, leak proof container and covered with 10% buffered formalin. Large specimens (colons, placentas, etc) may be submitted fresh but must be refrigerated after hours.

What are the three factors that must be considered when collecting specimen for examination?

Why is proper specimen Labelling important?

Pathology specimens should meet defined standards of patient identification and specimen labelling to ensure that the chain of information custody from patient to sample to laboratory to report is unbroken. … Inadequate or wrongly labelled specimens have the potential to result in serious harm to patients.

Why do we need to label products properly?

When it comes to marketing, the most important function of custom product labeling is to help consumers identify your brand. Keeping a consistent logo, font, color scheme, and other packaging elements between products provides consistency across your company’s selection.

What is the importance of accurate Labelling and recording of the test?
