Visible to the naked eye

Macroscopic

1

Visible only with a microscope

Microscopic

2

Distance between the specimen and outer objective lens

Working distance

3

The ability of a lens system to show fine details of the object being observed

Resolution

4

Area visible when you look through microscope

Field

5

Enlarging the size of something

Magnification

6

Used to separate liquid from solid using a high speed spinning process

Centrifuge

7

Liquid portion of blood

Supernatant

8

Solid component of a sample such as blood cells

Sediment

9

2 types of centrifuges

Horizontal (swing arm) and angled

10

Turns off centrifuge at preset time

Timer

11

Sets the speed of centrifuge

Tachometer

12

If sample is spun too long or fast

It will rupture cells and morphology

13

If ran too slow or not long enough

Will not separate sample

14

Used to count cells

Cell counter

15

Measure the concentration of solids in a liquid

Refractometer

16

When using a refractometer with urine, it measures

Specific gravity (SG)

17

If using a refractometer, you measure

Total protein (TP)

18

SG and TP are directly proportional to it's

Conentration

19

Readings on the refractometer will always be

Greater than 0 (water is 0)

20

Specialized slide with etched grids is used to count white and red blood cells and platelets

Hemacytometer

21

Used to heat slides or samples

Bunsen burner

22

Keeps blood tubes at an even distribution

Blood rocker

23

Use liquid and dry reagents or slides that contain dry reagents

Blood chemistry machines

24

Reagent impregnated slides, pads, or cartilage

Dry system blood chemistry

25

Used lypholized reagent or already prepared liquid reagent

Liquid system blood chemistry

26

Use a bulk reagent and is most expensive

Unitized systems (vet test)

27

Used only if a single test is needed or emergency situations

Dedicated use analyzes

28

Available for use in the field

Handheld analyzer

29

Generates hematologist data for the CBC
Counts cells and determines hematocrit, HGB conc, and MCHC

Whole Blood Machines aka hematology machines
