Study Notes
CM Comprehensive Exam Study Notes
-
CSF Labelling and Department: CSF tubes labeled 3 are routinely sent to Microbiology.
-
Subarachnoid Hemorrhage vs. Traumatic Tap: A clear supernatant after centrifugation, and the presence of xanthochromia are more indicative of a traumatic tap than a subarachnoid hemorrhage, which is associated with clearing of fluid. Protein in the sample is not a useful differentiator.
-
Conditions with Normal CSF Glucose and Protein: Viral meningitis is most often associated with normal CSF glucose and protein levels.
-
Pellicle in Refrigerated CSF: A web-like pellicle in refrigerated CSF suggests tubercular meningitis.
-
CSF Cell Count: A total CSF cell count on a clear fluid should be reported as normal in the absence of additional factors or symptoms.
-
Hemorrhagic Serous Fluid vs. Traumatic Tap: The formation of a clot in the CSF, rather than clearing, suggests a hemorrhagic serous fluid as opposed to a traumatic tap. A diminished RBC count in successive aliquots is also less useful to distinguish these.
-
Oligoclonal Bands: The presence of oligoclonal bands in CSF but not in serum is associated with multiple sclerosis.
-
CSF Lactate: Viral meningitis is more consistently associated with lower CSF lactate levels compared to other causes like bacterial meningitis.
-
Neurosyphilis Test: The test of choice for detecting neurosyphilis is the VDRL test.
-
Elevated CSF Protein: Elevated CSF protein values are seen in conditions like meningitis, multiple sclerosis, and fluid leakage, but not always in CNS malignancy.
-
CSF Differentiation: CSF can be differentiated from serum by the presence of globulin.
-
Spermatozoa Maturation: Spermatozoa maturation occurs in the seminiferous tubules.
-
Semen Enzymes: Enzymes for semen coagulation and liquefaction originate from the seminal vesicles.
-
Temperature for CSF: The freezing temperature is a factor routinely sent to the CSF tubes labelled 3.
-
Time for Semen Liquefaction: Liquefaction of a semen specimen should take place within 1 hour.
-
-glucosidase Measurement: This enzymatic measurement aids in detecting disorders related to the seminiferous tubules, epididymis.
-
Motility Rating: Rapid, straight-line motility is recorded as 4.0
-
Common Cause of Male Infertility: Varicocele is the most common cause of male infertility.
-
Sperm Concentration: The lower limit of normal sperm concentration is 15 million per milliliter.
-
Sperm Morphological Abnormality: Tapering of the sperm head is the most frequent morphological abnormality associated with varicocele.
-
Semen Analysis Results: Abnormal results (volume, liquefaction, pH, motility) suggest analysis variation and should be verified.
-
Seminal Fluid Analysis WBCs: The upper limit of normal for WBCs in seminal fluid analysis is 1 x 106/mL.
-
Carbohydrate Measurement in Semen Analysis: Fructose level is clinically useful when performing a seminal fluid analysis.
-
Reagent Strips: When using reagent strips, maintain the strips at room temperature, and store in dark airtight containers; blot on tissue following use and do not expose strips to moisture.
-
Other Tests: The information discusses several other clinical tests, conditions, and factors relative to a comprehensive exam.
