Important tips for collecting samples
General instructions:
-
Correctly collected samples should be sent to the laboratory within business hours without delay in order to avoid overgrowth or loss of susceptibility to pathogens, in order to ward off false results.
-
Samples should be collected from the correct anatomical sites using appropriate techniques to avoid contamination at the source of the sample
-
Samples must be collected before antibiotics are given and if antibiotics are given, this is indicated on the application form.
-
Collected samples should be of sufficient size and placed in an appropriate container.
-
Each sample must be accompanied by a complete application form with all required data on the sample form.
Instructions for some popular culture separately:
Urine culture:
- Collect 2-10 ml of mid-urinary urine into a sterile container, preferably early morning urine to enable the organism to multiply in the bladder prior to collection.
- If this is not possible, a 3-hour period should elapse after the last urination.
- Male patients should cleanse the glans penis with ordinary soap and water after drawing the sample, biopsy or swab.
- Female patients should also disinfect the labial folds and vulva.
- Dispose of the first portion of the excreted urine and collect the urine halfway directly into a sterile bottle.
- Note: The sample must arrive at the laboratory within 1 hour after collection. In case of delay, store at 4°C for no more than 24°C
Nasal swab for C&S.
- The swab should be moistened with sterile saline before sampling. Roll the swab over the mucous membrane of the nasal cavity. Replace the swab in the swab transfer medium and send the sample to the laboratory immediately
Throat swab for bacterial culture:
- Carefully insert the swab into the mouth with pressure on the tongue.
- Then rub a swab on each area of the tonsils and posterior pharynx.
- Samples should be taken from any area with exudate.
- Do not allow the swab to touch the tongue or lips.
- Replace the swab in the center of the swab transfer and send it to the laboratory immediately
Sputum culture for expectoration :
- Ask the patient to rinse and gargle with water.
- Instruct the patient to cough deeply to produce a lower respiratory specimen and collect early morning sputum in a sterile container.
- Send an immediate sample to the laboratory. If delay is unavoidable, store in the refrigerator for no longer than 24 hours.
vaginal swab:
- High smear from the vagina
- Wipe off the excess amount of secretion/discharge to obtain secretion from the mucous membrane of the vaginal vault using a sterile swab
Sputum culture for AFB
- It is preferable to collect sputum when the patient wakes up in the morning. Gargle the mouth before collecting sputum.
- Ask the patient to spit directly into a sterile container. Ensure that the phlegm is sputum and saliva.
- Send the sample immediately to the laboratory. If delay is unavoidable, store in the refrigerator until delivery as soon as possible
