  3. Test requisition • Test requisition : is the request by a competent authority made to laboratory for performing test which is needed for the diagnosis or prognosis of the patient . • Types of test forms : 1- hematology form 2- Chemistry form 3- Serology & virology form 4- Culture & sensitivity form 5- Hormones form 6- Urine analysis form 7- Stool analysis form 8- Multipurpose form

  4. General feature of the test forms • Every form included these features : 1- general information : related to the patient & the ward 2- hospital name 3- form’s type 4- clinical diagnosis 5- Processing type 6- date , time & name of the sender 7- tests to be done 8- analyzer information

  19. Specimen collection • Phlebotomist : the person who trained to enters a vein through needle to extract blood . • Types of specimen : 1- blood 7- body fluids 13- vaginal swab 2- sputum 8- throat swab 14- abscesses & 3- CSF 9- ear swab wound swab 4- fecal 10- eye swab 5- urine 11- mouth swab 6- semen 12- nose swab
