Question | Answer |
CSF is collected utilizing this procedure | lumbar puncture |
This location is routinely used for the collection of CSF | L3, L4, L5 |
This number of sterile tubes are collected during CSF collection | 3 |
The CSF tubes are sent to these departments | chemistry, microbiology, hematology, serology |
CSF hematology tubes must be tested within | immediately, STAT, or within an hour |
The cell count most commonly done on CSF is | WBC count |
The cells found in normal CSF are | 70% lymphocytes, 30% monocytes |
The finding of these cells in CSF are abnormal | neutrophils, macrophages, blast, lymphoma, ependymal, eosinophils |
A high CSF count consisting mainly of neutrophils indicates | bacterial meningitis |
A CSF with a moderately elevated WBC count and a high % of lymps and Monos suggest | meningitis; viral tubercular, fungal, or parasitic origin, multiple sclerosis |
CSF sample with increased eosinophils indicate | parasitic, fungal infections, foreign material, shunts and medication |
The normal value for CSF protein is | 15 - 45 mg/dL |
CSF gamma globulin is primarily | IgG |
IgM and beta lipoproteins are found in normal CSF | False |
These are the two most common causes of elevated CSF protein | meningitis and hemorrhage |
Name 2 routinely used techniques for measuring CSF protein are | turbidity production or dye binding |
What will CSF protein electrophoresis provide | separation of protein |
Normal CSF glucose vs. plasma glucose is | CSF glucose value is 60% to 70% of plasma glucose |
A high CSF glucose is a result of | plasma elevation |
A low CSF glucose is a result of | Meningitis; alteration of glucose transport across the blood brain barrier and increased use of glucose by the brain cells |
Name all the immunological procedures used for CSF testing | ELISA (enzyme linked immuno sorbent), BAT (bacterial antigen test), Latex aggulation, FTA-ABS |
What is the name of the procedure used to diagnose neurosyphilis | Serologic testing, FTA-ABS |
Name 2 reasons why seminal fluid is analysed | infertility and post vasectomy |
What parameters are used when evaluating infertility | Volume, Viscosity, pH, Motility, Morphology |
Presence of semen can be determined by the presence of this enzyme | prostatic acid phosphatase |
What is another name for synovial fluid | joint fluid |
Synovial fluid will clot | False, because synovial fluid doesn't have fibrinogen |
What departments are synovial fluid sent to | Microbiology, hematology, chemistry, and serology |
Low glucose levels in synovial fluids may indicate what | inflammation or septic disorders |
Blood glucose vs. synovial glucose | close but should not be more than 10mg/dL lower than blood value |
Name additional chemistry tests can be ordered on synovial fluid | Total protein and uric acid |
What role does microbiology department play with regard to synovial fluid | detection of organisims |
Name 3 closed body cavities | Plural, pericardia, peritoneal |
Body cavities are lined with ______ membranes | serous |
Name the procedure name for an abdominal cavity aspiration | paracentesis |
Name the procedure name for the collection of pleural cavity | thoracentesis |
Classify effusions of serous fluid | Transudate and exudate |
Effusion that form a systemic disorder that disrupts filtration and re absorption of fluids is | Transudate |
Effusion that forms because of a condition involving the cavity membranes is called | exudate |
Name the test(s) that is useful for differentiate between a hemothorax and a hemorrhagic exudate | hematocrit |
Name commonly ordered chemistry tests on pleural fluid | glucose, pH, ADA, and amylase |
Name the procedure for collecting amniotic fluid | amniocentesis |
What is the name of the test that can determine if a preterm delivery can be safely concidered | L/S ratio (lecithin-sphingomylein) |
Routine fecal screening test include | microscopic, macroscopic, and chemical analysis |
The term "occult" means | not seen/ hidden |
What is the normal pH of stool | 7 to 8 |
Name the test that is useful for differentiating pleural fluid transudates and exudates | pleural fluid cholesterol, fluid serum cholesterol ratio; and the pleural fluid and serum total bilirubin ratio |
