COLLECTION, TRANSPORT AND EXAMINATION OF SPECIMEN
If pathogens are to be isolated successfully, the type of specimen, its collection,time and method of its dispatch to the laboratorty must be correct. Adequate information about the patient’s condition and antimicrobial treatment must also be sent in the Specimen.
Type of specimen The correct type of specimen to be collected will depend on the pathogens to be isolated. For example: a cervical not a vaginal swab is required for the most successful isolation of N.gonorrhoeae from a woman.
:sputum not a saliva is essential for the isolation of respiratory pathogens.
Time of collection
Specimens such as urine and sputum are best collected soon after a patient wakes when organisms have had the opportunity to multiply over several hours.
Blood for culture is usually best collected when a patient’s temperature begins to rise.
