Renal and digestive labs
Thu, May 13, 2027 · Week 17 · Human Anatomy & Physiology (Human Body Systems)
Today's goal: Run urinalysis and enzyme-digestion labs to connect filtration and digestion to health.
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.
Urinalysis results (simulated patient sample), with normal range:
- Glucose: negative | normal range: negative. Result normal.
- Protein: 2+ (about 100 mg/dL) | normal range: negative to trace (under 15 mg/dL). Result high, a sign of failing filtration.
- pH: 6.0 | normal range: 4.5 to 8.0. Result normal.
- Blood: trace | normal range: negative. Result slightly high.
- Specific gravity: 1.012 | normal range: 1.005 to 1.030. Result normal.
Enzyme-digestion test:
- Tube with amylase + starch: iodine stayed amber (starch broken down). Digestion occurred.
- Control tube, no amylase: iodine turned blue-black (starch remained). No digestion.
Gel electrophoresis, PKD markers:
- Patient lane showed a band at the affected-allele position that matched the PKD1 marker lane.
- Interpretation: the band pattern is consistent with a PKD1 variant linked to polycystic kidney disease.
What the table shows together: high urine protein plus a PKD1 band pattern points to kidney filtration that is being damaged by polycystic kidney disease.
(Tip: always read each urinalysis value against its normal range; a number means nothing until you say whether it is inside or outside normal.)
| Test | Result | Normal range | Reading |
|---|---|---|---|
| Urine glucose | negative | negative | normal |
| Urine protein | 2+ (~100 mg/dL) | negative to trace (<15 mg/dL) | high, failing filtration |
| Urine pH | 6.0 | 4.5 to 8.0 | normal |
| Urine blood | trace | negative | slightly high |
| Specific gravity | 1.012 | 1.005 to 1.030 | normal |
| Amylase + starch | starch broken down | n/a | digestion occurred |
| PKD1 gel band | band at affected-allele position | n/a | consistent with PKD1 variant |
This model shows the level of evidence and organization needed to complete: Records urinalysis dipstick readings against a normal range, notes enzyme-digestion results, and interprets electrophoresis bands for PKD markers in one combined table.
- Name the variables and include units.
- Enter observations without changing the raw values.
- Check labels, calculations, and patterns before interpreting the data.
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: Submit your combined lab data table on Schoology.

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: Interpreting urinalysis dipstick results against a normal range.
- 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.
