Sample collection site

Male patients ejaculate into a specimen container, avoiding lubricants, condoms, or any other potentially contaminating materials. Usually, men need to refrain from ejaculating for at least 2 days prior but less than 7 days before collecting the specimen.

The specimen must not be refrigerated but kept as close to body temperature as possible by placing the container in a pocket and delivering it to the laboratory within 60 minutes. Patients are instructed to cough up sputum from as far down in the lungs as possible.

A health practitioner may assist the patient in some situations. This is best accomplished first thing in the morning before eating or drinking, by taking several deep breaths before expectorating into the collection cup.

Sputum should be relatively thick and not as watery as seen when producing saliva. Patients usually collect this sample themselves during toileting, following instructions to prevent the sample from becoming contaminated from other material in the toilet bowl.

Patients may also be told to avoid certain foods during the test period. Depending on the test, patients may be instructed to collect the sample in a container, scoop a small portion into a vial, or smear a small amount on special test paper.

Wash your hands well after handling the sample. Most urine specimens are collected by having the patient urinate into a container or receptacle. To keep the sample from becoming contaminated by materials outside the urinary tract, patients are given instructions on how to clean the genital area and void a bit of urine before collecting the specimen into the container.

If a urinary catheter is required, a health practitioner is usually responsible for insertion. Collecting the urine specimen is awkward but not in itself uncomfortable An infection, however, can create a burning sensation during urination.

For certain tests, hour urine samples are collected at home and must be refrigerated during the collection process. Remember to wash hands well after collecting the specimen. This type of sample may be collected using a swab or, if a larger volume is needed for testing, patients may be instructed to expectorate into a container without generating sputum.

This is a combination of saliva and oral mucosal transudate material crossing the buccal mucosa from the capillaries that is also collected from the mouth. For example, a rapid HIV test uses oral fluid. The patient collects the sample by using a special device to swab around their outer gums.

This type of sample may be collected using a special sweat stimulation procedure that is painless and allows sweat to be collected into a plastic coil of tubing or onto a piece of gauze or filter paper. It is then analyzed for the amount of chloride in the sweat. Elevated levels of chloride suggest a diagnosis of cystic fibrosis.

Some samples are collected by simply running a swab over the affected area. The sample may be sent to a laboratory for analysis although a few tests can provide in-office results in just a few minutes. Throat, nasal, vaginal, and superficial wound cultures, for example, are obtained in this way.

The procedures, while they may sometimes be uncomfortable, are generally quick, relatively painless, and have no after-effects. Samples of vaginal secretions are obtained by running a cotton swab over the walls of the vagina; cervical cells for a Pap test are obtained using a cotton swab and spatula or a tiny brush.

Endometrial tissue samples are obtained by inserting a thin, flexible, hollow tube into the uterus, during which you may feel a slight pinch or brief cramping. Patients may feel some emotional and physical discomfort during this procedure.

If you are physically uncomfortable, discuss this with your healthcare provider. The specimen is collected by running a swab over the area of interest and processed for testing, such as cultures.

If the throat is sore, the sample collection, brief as it is, can be uncomfortable. Similarly, a nasal swab may be a bit uncomfortable as the swab is inserted and reaches areas inside the nose that are typically never touched.

Try to remember that the discomfort is temporary and ask your practitioner if there are ways to minimize any soreness that may result. If a wound or sore is located in the outer layer of skin, the specimen is typically collected on a swab by brushing the swab over the area and gathering a sample of fluid or pus.

Touching the open wound area may be temporarily painful since the wound is likely to be tender and sore. If a wound or infection is deep, however, a needle and syringe may be used to aspirate a sample of fluid or pus from the site.

Blood specimens are obtained in minimally invasive procedures conducted by specially trained physicians, nurses, or medical personnel. Collection of tissue specimens is a more complex process and may require a local anesthetic in order to obtain a specimen.

Because of the nature of these collections techniques, some pain or discomfort may be involved. Knowing what the procedure involves may help alleviate some anxiety when having to undergo these types of sample collections. For more on this, see the article Coping with Test Pain, Discomfort, and Anxiety.

Blood samples can be collected from blood vessels capillaries, veins, and sometimes arteries by trained phlebotomists or medical personnel. The sample is obtained by needle puncture and withdrawn by suction through the needle into a special collection tube.

Some specimens may be obtained by a finger puncture that produces a drop of blood, such as that used for glucose testing.

The procedure usually takes just a few minutes and hurts just a bit, typically when the needle is inserted or from the puncture of a lancet.

See Tips on Blood Testing for more information. Samples of tissue may be obtained from a number of different body sites, such as breast, lung, lymph node, or skin. Depending on the site and the degree of invasiveness, some pain or discomfort may occur.

The time required to perform the procedure and for recovery can also vary greatly. These procedures are conducted by healthcare providers who have had specialized training. Tissue biopsies can be collected using procedures, such as:. A sample of cerebrospinal fluid is obtained by lumbar puncture, often called a spinal tap.

It is a special but relatively routine procedure. It is performed while the person is lying on their side in a curled up, fetal position or sometimes in a sitting position. The back is cleaned with an antiseptic and a local anesthetic is injected under the skin. A special needle is inserted through the skin, between two vertebrae, and into the spinal canal.

The health practitioner collects a small amount of CSF in multiple sterile vials; the needle is withdrawn and a sterile dressing and pressure are applied to the puncture site. The patient will then be asked to lie quietly in a flat position, without lifting their head, for one or more hours to avoid a potential post-test spinal headache.

The lumbar puncture procedure usually takes less than half an hour. Discomfort levels can vary greatly. The most common sensation is a feeling of pressure when the needle is introduced. Let your healthcare provider know if you experience a headache or any abnormal sensations, such as pain, numbness, or tingling in your legs, or pain at the puncture site.

Other body fluids such as synovial fluid, peritoneal fluid, pleural fluid, and pericardial fluid are collected using procedures similar to that used for CSF in that they require aspiration of a sample of the fluid through a needle into a collection vessel.

These are generally more complex type of collections and often require some patient preparation, use of a local anesthetic, and a resting period following sample collection. For details, see the descriptions for arthrocentesis , paracentesis , thoracentesis , and pericardiocentesis.

Both types of samples are most often collected from the hip bone iliac crest. In some instances, marrow collection may be collected from the breastbone sternum.

Almost all patients are given a mild sedative before the procedure, then asked to lie down on their stomach or side for the collection. The site is cleaned with an antiseptic and injected with a local anesthetic, treating it as a typical surgical field.

When the site has numbed, the health practitioner inserts a needle through the skin and into the bone. For an aspiration, a syringe is attached to the needle and bone marrow fluid is aspirated. For a bone marrow biopsy, a special needle is used to collect a core a cylindrical sample of bone and marrow.

After the needle has been withdrawn, a sterile bandage is placed over the site and pressure is applied. In some instances, the procedure may be repeated on the opposite hip bilateral bone marrow , most often done as part of the initial diagnostic workup.

The patient is then instructed to lie quietly until their blood pressure, heart rate, and temperature are normal, and then to keep the collection site dry and covered for about 48 hours.

A sample of amniotic fluid is obtained using a procedure called amniocentesis to detect and diagnose certain birth defects, genetic diseases, and chromosomal abnormalities in a fetus.

Amniotic fluid surrounds, protects, and nourishes a growing fetus during pregnancy. A sample about 1 ounce of amniotic fluid is aspirated by inserting a thin needle through the belly and uterus into the amniotic sac, collecting both cellular and chemical constituents that are analyzed to detect certain genetic abnormalities that may be present.
