spike

 [spīk]
1. a sharp upward deflection in a curve or tracing, as on the encephalogram.
2. the attachment of an intravenous infusion set to the bag containing the solution.

spike

(spīk),
1. A brief electrical event of 3-25 milliseconds that gives the appearance in the electroencephalogram of a rising and falling vertical line.
2. In electrophoresis, a sharply angled upward deflection on a densitometric tracing.
Drug slang noun A needle used to inject a drug
verb To inject a drug
Endocrinology See Insulin spike
Infectious disease noun A popular term for a sharply defined febrile peak
verb To develop a sharp febrile peak in temperature
Lab medicine noun A sharp peak in the or-region of a serum or urine protein electrophoresis, most common in malignant lymphoproliferative disorders—e.g., myeloma, Waldenström’s macroglobulinaemia, and monoclonal gammopathy of undetermined significance; spikes indicate monoclonality unless proven otherwise; spikes may not be seen if the Ig production is normally very low, as in IgD and IgE myelomas—the spike is obscured by the curves corresponding to more abundant IgG, IgA and IgM
Medspeak verb To place vascular access tubing into the appropriate port in an infusion bag—e.g., with Ringer’s solution
Neurology A sharply defined depolarisation on EEG
Pathology A term for a dense wedge-shaped plug of parakeratotic cells with a high nuclear:cytoplasmic ratio which may be seen overlying dyskaryotic cells, but may also be seen in trauma, HPV infection and after childbirth
Renal pathology A term for needle-like deposits of basement membrane material within the mesangial matrix in early membranous glomerulonephropathy, best seen with a PAS stain
Virology A projection on the surface of the virus that may be seen by electron microscopy, which corresponds to hemagglutinin or neuraminidase on the coat of influenza viruses
