Storage and transportation of samples:After the sample is collected, it should be transported to the corresponding laboratory for testing within 48 hours, and the storage temperature is 2-8°C. If it cannot be transported to the laboratory within 48 hours, it should be stored at -20°C or below and sent to the corresponding laboratory within one week. The sample should avoid repeated freezing and thawing.
INSTRUCTIONS
INSTRUCTIONS CONTINUED
- Mark the sample information on the tube.
- According to different sampling requirements, use a sampling swab to sample at the corresponding area. Hold the handle to gently insert the sampling swab into the sampling site, gently rotate the swab 3-5 times and slowly take out.
- Put the extracted sample into the sampling tube, break the swab at the breaking point and leave the swab head in the tube. Tighten the tube cap to complete the sampling.
- Freshly collected clinical specimens should be transported to the laboratory within 48 hours at 4 °C. Those that cannot be sent to the laboratory within 48 hours should be stored at -20 °C or below.
- The conventional sampling methods are as follows:
- Nasal swab: Insert the head of the swab gently into the nasopalatine part of the nasal canal, stop for a while, and then slowly rotate it out. Repeat to other nostril with a new swab. Once specimen is collected, immerse the head of the swab into the sampling solution, and discard the tail.
- Oropharyngeal swab: Use a swab to wipe the bilateral pharyngeal tonsils and posterior pharyngeal wall. Immerse the swab head in the sample solution and discard the tail.
- Mouthwash: Gargle in the mouth with 10ml of normal saline. Let the patient's head tilt back slightly and make an "Oh" sound. Let the saline rotate in the pharynx then collect the wash with an empty 50ml sampling tube.
- Nasal wash: While seated, the patient tilts their head slightly back and is injected with 50 ml of normal saline into one nostril with a pipette. Collector instructs the patient to simultaneously sound "K" to close the pharyngeal cavity. The patient then bows their head to let the saline flow out as the fluid is collected with an empty 50 ml sterilized tube. Repeat this process to wash the other nostril.
- Nasopharyngeal extract: Tracheal and bronchial secretions are often collected using this method. Mucus is drawn from the nasopharynx with a collector connected to a negative pressure pump. First insert the collector head into the nasal cavity, turn on the negative pressure, rotate the collector's head, and slowly push it out. Collect and draw the mucus, and rinse the collector three times with 5 ml of the sampling solution.
- Autopsy tissue specimens: Collect autopsy tissue specimens if necessary, to separate sample components. The specimen is autopsy tissue. Samples of mycoplasma, chlamydia, urea plasma: for males, inserts the sterilized swab into the urethra about 2cm, rotate, and take out. Let the material rest for several seconds. For females, wipe out the cervical mucus and inserts the sterilized swab into the cervical canal 1cm-2cm to take out material.
