Flashcards in Serology Deck (34):
1

Agglutination

The clumping of molecules or cells

2

Antibodies

Proteins secreted by white blood cells that attach to antigens

3

Antigen-Antibody response

A reaction in which antibodies attach to specific antigens

4

Antigen

Any foreign substance or cell in the body that reacts with antibodies

5

Cell surface protein

Proteins embedded in the cell membrane

6

Lines of convergence

A two dimensional view of the intersection of lines

7

Point of origin

A THREE dimensional view formed using lines of convergence

8

Red blood cells

Donut shaped cells that carry oxygen throughout the body

9

Satellite drop of blood

Secondary drop formed when some blood breaks free from the main contact drop of blood

10

White blood cells

Cells that police the body by destroying foreign materials

11

True or false. Correct the statement if it's false.

Blood typing is class evidence.

True

12

True or false. Correct the statement if it's false.

DNA blood testing is class evidence.

False
Individual

13

True or false. Correct the statement if it's false.

The Kastle-Meyer test can tell you if there is blood at the scene.

True

14

True or false. Correct the statement if it's false.

Blood consists of red blood cells, white blood cells and plasma.

True

15

True or false. Correct the statement if it's false.

When testing blood type, white blood cells are analyzed.

False
Red blood cells

16

True or false. Correct the statement if it's false.

Human red blood cells have no nucleus, while the red blood cells of all other animals have a nucleus.

False
Most other animals will not have a Nucleus

17

True or false. Correct the statement if it's false.

There is no difference in the look of blood dropped from 15 cm and from 150 cm.

False
15cm is smaller blood drop with no satellites and spines

150cm larger drop, many spines and satellites

18

True or false. Correct the statement if it's false.

Blood drops look the same on all surfaces

False
smaller on smooth surfaces

19

True or false. Correct the statement if it's false.

If a person is bleeding while running, the spines and satellites on the drops will point in the direction in which he is running.

True

20

True or false. Correct the statement if it's false.

A person with Type O blood has antigens for A and B.

False
Antibodies

21

True or false. Correct the statement if it's false.

Cast off blood looks similar to high velocity spatter.

False
Cast off roundish drops in a line
High velocity looks like a fine mist of blood

22

True or false. Correct the statement if it's false.

A person who has type B- blood can receive blood from a person who has O- blood.

True

23

True or false. Correct the statement if it's false.

The area of convergence can be determined by drawing lines from each of the blood drops through the long axis of each drop.

True but have to be drawn in the opposite direction of the satellites

24

Agglutinates

Clumps

25

What are the steps for testing for blood types?

1. Put blood in a tube.
2. Add antibodies.
3. Look for agglutination.

26

If the blood clumps or Agglutinates what does that tell you?

It is that type of blood

27

Using the K-M test what color will the swab turn if blood is present?

Bright pink or purple

28

What blood type is known as the universal donor?

O-

29

What does universal donor mean

Can donate blood to all other blood groups

30

What blood type is known as the universal acceptor?

AB+

31

What does universal acceptor mean?

Can accept blood from all different blood types

32

How can you tell the difference between arterial spurts from a cast off

Arterial spurts are separated by space.
Cast off will be a continuous line of drops.

33

What causes agglutination?

Antigen - antibody interaction

34

What is one difference between human and animal blood

Human blood has bigger plasma
animals have smaller plasma
