Non-anticoagulated venous blood or peripheral blood from finger or earlobe preferred. Prepare 3 thick and 3 thin smears on separate slides. EDTA blood can be used if slides are prepared within 1 hour of collection.

Prepare slides as follows:
THIN SMEARS:   Prepare at least 3 thin blood smears in the same manner as for a differential.

THICK SMEARS: Place a drop of blood on a slide.  Using the corner of a clean slide or applicator stick, spread the blood in a circle about the size of a dime. If proper thickness is achieved, ordinary print should barely be visible through the wet center.

Allow both thick and thin films to air dry without heating. The thick smear must dry 8-10 hours before staining.

Patient should not douche, use any medications or creams in the vagina, or have intercourse for 24 - 48 hours prior to specimen collection.  Specimen collection is not recommended during a patient’s menstrual cycle.

A vaginal smear from the mid lateral vaginal wall is the area of choice, therefore ensuring an accurate index evaluation. Obtaining the specimen from any other area will not always reflect an accurate or true maturation index.

After slide preparation, cytofixative spray must be applied immediately to ensure preservation.
Slides must be labeled with patient first and last name in pencil.
