c. Collect blood specimens using either a standard 10 cc disposable syringe with a 1- to 1½-inch needle (20 to 22 gauge), or by using a VacutainerTM system. When using a VacutainerTM system, ensure that multiple specimen needles and "red top" vacuum tubes are used. Ten cc of blood is sufficient for analytical testing. Do not take more than 5 cc from small, malnourished children. After blood is collected, it should be transferred to a polypropylene-type container and sealed with parafilm before transporting. All body fluids should be collected without violating antiseptic techniques. Also, prior to transporting specimens, collectors need to check specimen containers for paper labels IAW guidelines for labeling medical specimens. Collect blood specimens using the following materials equipment:
- Gloves.
- 10 cc sterile, disposable syringe.
- 1- to 1.5-inch sterile needle (20 to 22 gauge).
- VacutainerTM device (adapter with needle).
- Constricting band.
- Disinfectant pads, Betadine, or alcohol.
- Sterile 2×2-inch gauze pads.
- Labels.
NOTE
Gloves should be worn whenever handling medical specimens. Do not freeze liquid blood and urine specimens (ideal cooling temperature is between 35° and 40°F [2° to 4°C].)
d. Collect urine specimens using either a standard urine cup or by a urine catheter and urine cup. When collecting the specimen directly into a urine cup, the person must urinate into the cup until sufficient fluid is collected (40 cc of urine is preferable, although 10 cc can support analytical testing). When the person is unable to urinate, the catheterization technique is preferable. The catheterization technique is best performed in a clinical environment. As with other body fluids collected, urine must be kept cold. Do not freeze.
NOTE
For correct procedures on catheterization refer to STP 8-91W15-SM-TG.
e. Collect tissue specimens using sterile scissors and forceps or as directed by the attending physician.
(1) When casualties have unidentified skin lesions, photographs of the lesion(s) and overall photos of the extent of the lesion(s) should be taken, using color film before biopsy. A specimen of the lesion should be obtained. This is done by surgically removing a portion of the skin with a sterile pair of scissors and forceps.
