Given a Staging System of species A with age/somite ordered specimens 1, 2, 3, 4 and 5: When finding a new embryo which is developmentally difficult to settle between specimen 2 and 3 with more similarities to specimen 2, the new specimen is to be named as "specimen 2>3".
Even so, the very existence of intraspecific heterochrony means that absolute age usually cannot be considered to be a reliable criterion for ordering specimens in a developmental sequence [ 30].
To describe the external development of embryonic series I suggest the following protocol: Ordering: Primarily, specimens should be ordered by a comparative synopsis of the embryos' age and the development of reference organs, such as the number of somites, or as often used, the limb bud development [78] [79].
Computer-assisted histomorphometry was performed blind in random order of specimens with a light microscope (Olympus BX50) and stereological image analysis system (Cast version 2.1.4; Olympus).
Although this investigation aimed to intensively sample nematodes from the order Enoplida, specimens were only identified down to genus (at best) and our sampling regime focused on an infinitesimal small fraction of the deep-sea floor.

The lab report must include information about the patient, ordering physician, specimen collection, test method, results and interpretation in a format and language understandable to a general practice physician (Box 1).
