The electron microscope is a sophisticated instrument that can be used for the clinical diagnosis of inherited platelet disorders. Instances in which electron microscopy has been critical for identifying and characterizing genetic problems include platelet storage pool deficiency (SPD) which is due to a marked decrease or absence of the organelles storing adenine nucleotides, serotonin, and calcium destined for secretion during the platelet release reaction. The organelles are referred to as dense bodies because they are inherently electron opaque. As a result, platelet SPD is more rapidly and reliably diagnosed in the electron microscope than by any other technique. Giant platelet disorders have presented a bewildering array. The electron microscope has made it possible to separate the various types into distinct conditions based on the nature of platelet structural defects and inclusions found in leukocytes.
