Activate the safety device and properly dispose of the vacutainer holder with needle attached into a sharps container. Holding the needle in line with the vein, use a quick, small thrust to penetrate the skin and vein in one motion. Draw the desired amount of blood by pulling back slowly on the syringe stopper.

Release the tourniquet. Immediately apply pressure. Ask the patient to apply pressure to the gauze for at least 2 minutes. Transfer blood drawn into the appropriate tubes as soon as possible using a Blood Transfer Device, as a delay could cause improper coagulation. Secure patient to Papoose apparatus for stabilization if child is unable to sit upright on their own.

Select the collection site and proceed as routine phlebotomy. If the child is old enough, collect blood as in an adult. Probing is not recommended.

In most cases, another puncture in a site below the first site is advised. A patient should never be stuck more than twice unsuccessfully by a phlebotomist.

It is important to verify that the methods have been adequately validated. Some tests require larger quantities of blood, however, and it will often be necessary to collect blood by venepuncture from at least a sample of the population.

After collection, blood may be separated into several components, including serum, plasma, red cells, and white cells. The separation must be done shortly after the blood has been collected, and it is common for this procedure to be carried out close to where the samples have been collected or in a nearby field laboratory.

A sample of blood taken from a finger-prick may be collected in one of several ways, including:. Fingertips are swabbed with alcohol before pricking, and the first drop is wiped off.

Sufficient blood can be obtained for two thick, and two thin, malaria smears to do one or two haemoglobin level measurements for example, with the Haemocue®system or the older haematocrit tubes , to collect 50— microlitres of blood in a microtube or Microtainer®for serum, and to place a drop on filter paper World Health Organization, Filter paper samples need to be air-dried, before storing with silica gel.

Tubes with plasma or serum can be stored on dry ice, in a freezer, or in liquid nitrogen. The amount of plasma or serum recovered from a finger-prick sample will be sufficient to perform serological tests, such as enzyme-linked immunosorbent assay ELISA or Multiplex®assays, and is sufficient for the determination of some micronutrients such as vitamin A or zinc minimum serum requirements of 25—40 microlitres.

Establishing volume requirements for the tests to be conducted is a prerequisite. If repeated blood sampling is to be undertaken from participants during the course of a study, it is likely to be more appropriate ethically, and easier to maintain the co-operation of most study populations, if finger-prick, rather than venous blood, sampling is used.

While filter paper samples are satisfactory in many cases, the larger sample volumes from venous sampling are currently needed for some tests for example, tests for cell-mediated immunity, human leucocyte antigen HLA typing, bacterial cultures.

A variety of systems using an evacuated tube, such as Vacutainer®or Vacuette®collection tubes, and blood culture bottles are suitable for this purpose. For repeated sampling, it is also essential to provide feedback to the individuals involved, and to the community if appropriate, about the earlier results see also Chapter 9.

If multiple types of collection tubes are to be used, the order of draw should be written into the SOP to minimize cross-contamination of tube additives. Special care in handling and processing samples is needed if any DNA-based work is to be conducted, as the potential for cross-contamination between samples is high.

Blood for bacterial cultures is collected by venepuncture and delivered directly into blood culture bottles containing bacterial growth media, before incubation in the laboratory in either a conventional incubator or an automated incubator system such as the BACTEC®series.

Blood for immunological and genetic analysis can be collected as whole blood and stored in specialized tubes such as PAXgeneTMor TempusTMor, when only small volumes are available, as spots collected on filter paper for later analysis in a specialist laboratory. Special precautions should be taken when collecting blood.

Disposable gloves should be worn, a sharps box provided, and water and detergent should be available for use by those taking blood. All blood samples should be considered to be potentially infectious, and appropriate handling procedures must be employed to safeguard all those who will come into contact with the specimens during their collection, processing, analysis, or storage World Health Organization, Guidelines and drugs should be available for use in the event of a needle-stick injury or blood spillage.

Collection of cerebrospinal fluid CSF requires lumbar puncture, which must be performed by a clinically trained member of staff with prior supervised experience. Using aseptic techniques, CSF should be collected into a sterile container for prompt transfer to the laboratory for biochemical and microbiological analysis.

A summary of different methods that may be used for collecting urine and stool samples, with details of different container types, is given in World Health Organization, The methods considered for use in a particular survey should be discussed with those knowledgeable of local customs and taboos.

In some cultures, sensitivity regarding the collection or public display of stool specimens may be greater than that for blood. A container that is technically appropriate may not be acceptable in a particular study community for example, due to colour, transparency, or resemblance to a cultural design or pattern.

In advance of a survey, the proposed stool and urine containers should be shown to the village leaders, and the proposed methods of sample collection discussed. As with all field procedures, it is important to undertake pilot testing to ensure that the procedures planned will be acceptable both to the investigator and to the study population.

A potential hazard in doing this is that containers may be exchanged between individuals or, for example, one person may provide a sample for the whole family. It is difficult to rule out this possibility, but it is important for fieldworkers to stress the importance of participants adhering to the correct procedures and to be alert to possible problems.

Sample collection is vital to environmental research, as it allows scientists to determine the status of an ecosystem.

By collecting biotic and abiotic samples we can determine an ecosystem's health. You need to determine what type of sampling needs to be conducted, ensure that you have the proper equipment and use the proper measurement standards. Taking samples from a stream, for example, can determine how polluted it is and whether each native species is present.

There are three basic steps in sample collection: 1. Creation of a detailed sample collection plan, including when and where you will be going to do the collection, as well as why the samples need to be collected, 2. The collection of the samples in the field, and 3.

Ensuring that the samples collected are safely contained until they are ready to be used. Large or unwieldy samples may be split into reduced samples for use in the laboratory. Reduced samples are deemed representative of the whole.

If your sample size results in using excess money, time or resources to complete your experiment, it is what? Already have an account? Log in. The level of precision is the range in which the true value of a population is estimated to be.

The confidence level is the probability that the value of a parameter falls within a specified range of values. Everything you need to know on. A perfect summary so you can easily remember everything. The first learning app that truly has everything you need to ace your exams in one place.

Sample Collection: Definition and Importance Let's begin with the definition of sample collection. Systemic Sampling In systematic sampling , samples are taken at regular intervals. There are three types of quadrat used in environmental science: Open frame quadrats consist of a simple square frame, typically 1m 2 in size.

Sampling Methods When determining your sampling method, you need to determine the equipment needed, and biotic measurements you will make. Sampling Equipment This table provides a summary of equipment used for sampling biotic factors.

Measuring Equipment. Let's do a worked example. Sample Collection - Key takeaways Sample collection in environmental science refers to the collection of specimens from the environment.

Sample collection helps scientists understand the ecosystem and find evidence to support their theories. The most prominent types of sample collection are random and systematic sampling. Sampling locations need to be safe, accessible, and suitable. Sampling location is determined using transects or quadrats.

Sample collection involves specialised equipment and making biotic measurements using your data. For laboratory use, samples may need to be reduced, but remain representative of the whole sample.
