Specimen collectionPhlebotomist : the person who trained to enters a vein
through needle to extract blood .Types of specimen :1- blood 7- body fluids 13- vaginal
swab2- sputum 8- throat swab 14- abscesses &3- CSF 9- ear swab wound
swab4- fecal 10- eye swab5- urine 11- mouth swab6- semen 12- nose swab
Specimen collectionSpecimen collection is the first step in
proficiency surveillance. For issuing accurate and precise results, it is the job of the nurse or phlebotomist to make sure that the enumerated conditions are met and implemented in order to deliver a suitable sample for analysis so that an accurate and precise result will be issued.
Procedure of specimen collectionPre-collection check :1- review the request and identify the patient
by asking the name, seeing his ID and compare it with the request form .
2- Is there any special instruction / preparation needed for the patient. If so advice the patient accordingly
