Question

Harry, a 30-year-old male in good physical condition had a routine physical test for life insurance. CBC: Hb 15 g/dL, Hct 47%, RBC count 5.2 × 1012/L Platelet count 175 × 109/L, WBC 12 × 109/L

1- Consider how you would explain these results in a healthy male.

2- Are any of these results outside the reference range? If so, which one(s)?

3- If this were a newborn, would you change your evaluation? Why?

4- A WBC differential was performed: Neutrophils 58% Lymphocytes 32% Monocytes 6% Eosinophils 3% Basophils 1%

5- Are any of the WBC concentrations outside the reference interval (relative or absolute)? 6- Is there a need for reflex testing? Explain your answer.

Answer 1

Que1. Complete blood count is a test that counts the cells that make our blood , RNC , WBC , PLATELETS COUNT .

Its done diagnose any abnormalities in body like anemia ( low hb , hct or LOW RBC ) , infection (WBC raise ) , therapeutic effect of medication , during chemotherapy , keep eye on blood condition.

Healthy men must have their CBC values in reference range.

TEST. REFERENCE VALUE

1. RBC. 3.90-5.6 10*12 /L

2.HGB . 14-17.4 g / L

3.HCT 42-52%

4.MCV 80-100fl

5.MCH 28-34Pg

6.PLT . 150--400)× 10 *9 g/L

7 .WBC . 4.20- 10.80)× 10 * 9 g/L

Que 2. Yes , one these is out of range that is WBC normal range is 4.20-10.80)×10*9g/L, but patient vale is 12 × 10*9 g /L .

It represents the infection in body

Que 3. Yes , we have to change our evaluation because new born have different range of cells in body because of body requirements . Newborn are have undeveloped organs so their reference values will be different from adult. Like high HGB because lungs are underdeveloped .

Que 4. No, all value are in reference range.

Neutrophils = 55-70%

Eosinophils = 1-3%

Basophils = 0.5-1%

Lymphocytes= 20-35%

Monocytes =. 3%-8%

So, there is no elevation in blood value of the patient.

Qué 5.. Yes , there is need of reflex testing , performed as a part of the neurological examination asas to perform the spinal cord injury or any neurological disorders , because there is increased count of WBC which . Represent the infection in body ,so we need to do test , whether infection has spread to the brain or spinal cord .
