Other investigations commonly performed: serial neutrophil counts for suspected cyclic neutropenia, tests for antineutrophil antibodies, autoantibody screen (and investigations for systemic lupus erythematosus), vitamin B12 and folate assays. Rectal examinations are usually not performed due to the increased risk of introducing bacteria into the blood stream and the possible development of rectal abscesses. Classification
Generally accepted reference range for absolute neutrophil count (ANC) in adults is 1500 to 8000 cells per microliter (µl) of blood.
In this variant of human foot anatomy, the second toe extends further out than the great toe. This can make it harder to find shoes with adequate space around the toes. Treatment
Subungual hematomas can resolve on their own, without treatment being necessary. If they are acutely painful, they may be drained.Subungual hematomas are treated by either making a hole through the nail into the hematoma (trephining) within 48 hours of injury, draining the blood and releasing the pressure, or, less conservatively,  by removing the entire nail.In hospital or medical setting, trephining is generally accomplished by using an electrocautery device or an 18-gauge needle. If neither of these is available a heated (red hot) paper clip can be used to drain the blood underneath of the nail. To do this the tip of a paper clip needs to be heated till its red hot and (the red hot) paper clip gently placed on the center of the hematoma (center of the black area underneath of the nail). A hole will appear in the nail and the blood will drain, relieving the pressure. The hole has to be covered with sterile dressing and the nail should be kept dry afterwards.Removal of the nail is typically done when the nail itself is disrupted, a large laceration requiring suturing is suspected, or a fracture of the tip of the finger occurs. Although general anesthesia is generally not required, a digital nerve block is recommended if the nail is to be removed.
