Bloodwork and ranges
Wed, Oct 14, 2026 · Week 8 · Principles of Biomedical Technology (Principles of Biomedical Science)
Today's goal: Identify routine blood tests and their normal ranges before the PLTW clinical-data task.
This is a model of the work you should turn in today. Use it to check your own: match the structure and the level of detail, do not copy it. Your data and wording should be your own.
Three blood markers, ranges, and an out-of-range meaning:
- Fasting glucose: normal 70 to 99 mg/dL. Out of range high (above 125 fasting) can indicate diabetes.
- Total cholesterol: desirable below 200 mg/dL. Out of range high can indicate increased cardiovascular risk.
- White blood cell count (part of a CBC): normal about 4,500 to 11,000 cells/uL. Out of range high can indicate an infection.
Each marker has a unit, so a reader knows exactly what the number means.
| Marker | Normal range | Unit | Out-of-range condition |
|---|---|---|---|
| Fasting glucose | 70 to 99 | mg/dL | Diabetes (if high) |
| Total cholesterol | below 200 | mg/dL | Cardiovascular risk (if high) |
| WBC count | 4,500 to 11,000 | cells/uL | Infection (if high) |
This model shows the level of evidence and organization needed to complete: A quick exit ticket listing three blood-panel markers with their normal ranges and units, plus one clinical condition linked to an out-of-range value for each.
- Name the prompt or task.
- Answer it directly with the key evidence.
- Check that the response matches the requested format.
Keep the structure. Replace the question, facts, measurements, and evidence. Then recheck units, vocabulary, and whether the conclusion goes beyond the evidence.
Also due today: Hand in the exit ticket before leaving class.
Claim ceiling: Today's evidence supports a classroom claim about today's lesson. It cannot prove causation, diagnose a real patient, or justify action outside this room.
One exam-style question that uses exactly what you practiced today. Try it before you reveal the answer, then read why each choice is right or wrong.
Tap an answer to see the full explanation. Nothing is recorded or graded.
It builds this reusable test skill: Knowing normal blood-panel ranges and their units.
- Name the concept or data pattern being tested.
- Cross out choices that violate that rule or the evidence.
- Justify the best remaining choice before checking the answer.
