Q

M:E ratio

what is counted as myeloid, what isn’t

what is examples of erythroid

A

M:E

M=myeloid, blast count as myeloid
-not lymphs/monos

E=normo/erthroblast/rubricytes

The normal M:E ratio in adults varies from 1.2:1 to 5:1 myeloid cells to nucleated erythroid cells. An increased M:E ratio (6:1) may be seen in infection, chronic myelogenous leukemia or erythroid hypoplasia. A decreased M:E ratio (<1.2-1) may mean a decrease in granulocytes or an increase in erythroid cells. M:E ratios are somewhat higher in newborns and infancy than in later childhood and in adults. It is important to note that lymphocytes, monocytes and plasma cells are not included in the M:E ratio.

What is the order of draw for multiple evacuated tubes?
Blood culture (aerobic) blood culture (anaerobic), blue red, green stopper lavender, gray When collecting multiple tubes of blood, a specified “order of draw” protocol needs to be followed to diminish the possibility of cross contamination between tubes caused by the presence of different additives. Errors in the order of draw can affect laboratory test results.

Chromatography 1.) liquid-liquid (aqueus,organic) 2.)ion exchange (wt,size,charge) 3.)gas-liquid (volatility, rate diffusion) -blood alcohol, drugs abuse use w/MS 4.)Thin layer(Rf sub/solvent) 5.)high performance liquid(pumped thru columns under high pressure)
107
Method to separate proteins on charge and size direction on isoelectric point and pH of buffer cellulose acetate most common
can separate aminos, serum proteins, lipo,glyco,nuclei,hmg, isoenzymes
108
3 types of electrochemistry methods
potentiometry: voltage, diff between ref and indicator, pH/glass, K valinomycin amperometry: current flowing, O2 electrode, platinum coulometry: titration, Ag+ ions cause tiration to stop; Cloride
109
Method/name of cell passing thru current creating pulse=cell size MCV meausred directly=cell size RBCs/PLTs counted in RBC bath WBC/nRBC counted in WBC bath
electronic impedance/Coulter
110
Optical scatter, 5pt diff light scatter... forward/side...
Flow cytometry forward cell size side interior
111
RBC left shift.. right shift...
leftshift microcytes right shift macrocytes
112
Method that uses light in a fluid medium to measure cells laser excites fluorochrome forward scatter is diffraction/refractions=size side scatter is reflection=granularity
113
air displacement: air remains between the piston and the liquid. Positive displacment:piston is in direct contact
114
Osmolality=mOsmol/kg of H2O Normal range 275-295 mOsm/kg 1.86(NA) + GLU/18 + BUN/2.8. -NA, GLU, BUN , 1.86, 18, 2.8 Osmolality of NA 150 Glu 180 BUN 14 294 mOsmol/kg
115
Proficiency testing is required by CMS under CLIA, approved by HHS Usually done 3 times per year, keep 2yrs 80% lab/100% BB 2/3 fail or 2 consec same analyte

EEOC equal employment opportunity commission FLSA fair labor standards act title 7 civil rights act ACT of 1963 prohibiting discrimnation, FMLA 12 weeks unpaid job leave in 12mth period COBRA consolidated omnibus budget reconcilation act Act that provide health insurance 18 or 36mths expect for gross misconduct HIPAA health insurance portability and accountability act
117
Race: rescue, alarm/call, contain, extinguish Pass: pull, aim, squeeze, sweep base
118
Nongausian skewed pos or neg, skews alter these two, but not this
Alter mean and median, not mode
119
Immunoassay/immunochemical use ab to bind ag of intereste visa/versa Immunoprecipitation/agg: clumping of ab particles to which specific antigenic labels are attached Immunoelectrophoresis: immunoprecipitation in which ag are separated by migration in electric field, followed by ab reaction by immunodiffusion Immunodiffusion: spreading movement of ab and/or ag in suport medium Immunofixation: western blot Heterogeneous IA: liquid/solid phases to separate Homogenous IA: labeled analyte does not require separation of bound free ag Radioimmunoassay: RIA Enyzme mulitiplied immunoabsorbent assay: ELISA Immunofluoresence/fluroimmoassay Immunohistochemistry Nephelometry: light scattering ag/ab aggregation
