Hematology Worksheets Results Interpretation

PRACTICAL INSTRUCTIONS:

Please complete all sections of the exam before submitting the document to Canvas. You are allowed to use resources to complete the exam.

Section I: Peripheral Blood Smear Review (10)

Given the associated documents, complete a virtual smear review for each of the 10 “slides” as indicated below:

WBC DIFFERENTIAL:

There are 60 individual images included for the WBC differential section of each “slide. Identify each of the cells included per the included instructions and record your results in the tables below.

PLATELET ESTIMATE:

Using the RBC morphology images, complete platelet estimates using the semi-quantitative descriptive ranges as described below. Record your results in the indicated space.

· Extreme marked decrease (<20.0 x 103/uL) · Marked decrease (20 – 50 x 103/uL) · Decreased (50 – 150 x 103/uL) · Normal (150 – 400 x 103/uL) · Increased (400 – 700 x 103/uL) · Markedly Increased (>700 x 103/uL)

· Note presence of platelet clumps if seen

RBC MORPHOLOGY:

Report RBC morphology using the procedure from your clinical site. Assume that each of the 4 images represents an individual high-power field from the same slide. Record RBC morphology in the indicated space.

Section III: Procedure Interpretation

Given the following GENERIC PROCEDURES, review the associated samples and questions and provide the best answer or resolution. Each set of questions is associated with a specific procedure. See Canvas for the two procedure documents.

NOTE: These generic procedures are meant to simulate real procedures used in the clinical laboratory; the referenced procedures within each may not exist in this context.

· CBC Automation: Results Verification and Reflex Testing

· Routine Coagulation Results Verification

SECTION I: PROCEDURE INTERPRETATION

CBC Automation: Results Verification and Reflex Testing

Given the following CBC results, note whether they would be autoverified or held for manual verification, according to the procedure. If they would be held for manual verification, note which parameter (or instrument flag) would be the reason, what kind of reflex testing is necessary, and whether there are any critical results which need to be calledd.

Instrument flags: NONE

Autoverification passed: YES / NO

If NO, what parameter(s) held and why:

What reflex testing is necessary?

Are there any critical values which must be called/documented?

Specimen 2

Instrument flags: Leukocytosis, IG Present

Autoverification passed: YES / NO

If NO, what parameter(s) held and why:

What reflex testing is necessary?

Are there any critical values which must be called/documented?

Specimen 3

Instrument flags: NRBC Present, IG Present, Blasts/Abn Lympho?, RET Abn Scattergram

Autoverification passed: YES / NO

If NO, what parameter(s) held and why:

What reflex testing is necessary?

Are there any critical values which must be called/documented?

Specimen 4

Instrument flags: Blasts/Abn Lympho?, Left Shift?, Atypical Lympho?

Autoverification passed: YES / NO

If NO, what parameter(s) held and why:

What reflex testing is necessary?

Are there any critical values which must be called/documented?

Specimen 5

Instrument flags: Eosinophilia, IG Present, Blasts/Abn Lympho?

Autoverification passed: YES / NO

If NO, what parameter(s) held and why:

What reflex testing is necessary?

Are there any critical values which must be called/documented?

Specimen 6

Instrument flags: NONE

Autoverification passed: YES / NO

If NO, what parameter(s) held and why:

What reflex testing is necessary?

Are there any critical values which must be called/documented?

Specimen 7

Instrument flags: IG Present

Autoverification passed: YES / NO

If NO, what parameter(s) held and why:

What reflex testing is necessary?

Are there any critical values which must be called/documented?

Specimen 8

Instrument flags: Neutrophilia, Monocytosis, Leukocytosis, IG Present, Left Shift?

Autoverification passed: YES / NO

If NO, what parameter(s) held and why:

What reflex testing is necessary?

Are there any critical values which must be called/documented?

Specimen 9

Instrument flags: RBC Agglutination?, Turbidity/HGB Interfer?

Autoverification passed: YES / NO

If NO, what parameter(s) held and why:

What reflex testing is necessary?

Are there any critical values which must be called/documented?

Specimen 10

Instrument flags: WBC Abn Scattergram, IG Present, Blasts/Abn Lympho?, Left Shift?

Autoverification passed: YES / NO

If NO, what parameter(s) held and why:

What reflex testing is necessary?

Are there any critical values which must be called/documented?

Routine Coagulation Testing: Results Verification
