A dead human body has been discovered in the woods near your home. No, you are not a homicide suspect; rather you are an expert hematologist, and the body is still warm. Implausibly, this adult corpse has no gender cues (no sexual organs, and skeletal features that are in between those expected for males or females). How can you assist the detectives in determining the gender of this person,
using the hematology lab in your garage?
What will be an ideal response?
Assuming you can collect and centrifuge the blood soon, prior to clotting and decay, a hematocrit may provide clues. While a differential white cell count is independent of gender, hematocrit, hemoglobin concentration, and red cell count are all slightly lower in females. See Figure 16.3 in this chapter.
