Step 3: Remove the needle from the syringe and pull the plunger down to draw air into the syringe to apply pressure. Then, continue to insert the needle into the syringe, inject the puncture fluid out of the prepared slide quickly. Finally, use another slide to spread the specimen on the slides with the specimen. Step 4: After making the slides, fix the slides, stain the slides and identify the results for the patient.
