Summary

1. Active inflammation or infection: CRP 9.07 mg/dL (about 90 mg/L; normal is under 0.5), procalcitonin 0.38 ng/mL, and WBC 14.7.
2. Microcytic anemia: Hb 9.1, MCV 68.7, MCH 22.8.
3. Pyuria on urine microscopy (WBC 18-20/HPF) with a negative dipstick. The analyzer flagged "UTI?".
4. Very high triglycerides (589 mg/dL) with normal cholesterol.
5. Coagulation, kidney, liver and thyroid tests are normal.

CBC (Sysmex XN)

• The Mentzer index is MCV/RBC = 68.7/3.99 = 17.2. A value above 13 favors iron deficiency over thalassemia trait.
• The normal RDW and the low RBC count leave thalassemia trait, mixed causes, or anemia of inflammation possible. CRP is high, so ferritin may be falsely raised.
• Platelets are normal, so there is no reactive thrombocytosis.
• The analyzer flag "HGB defect?" is a generic microcytosis prompt.
• Next steps are a peripheral smear, reticulocyte count, serum iron, TIBC and ferritin, and Hb HPLC/electrophoresis if iron studies are normal or the anemia does not respond. Ask about diet, milk intake, worms and family history.

Coagulation (blood bank form)

• PT 11.6 s, INR 1.01: normal.
• APTT: not reported (crossed out).
• This is reassuring if it was done before a procedure. If a bleeding disorder is suspected, an APTT is still needed.

Biochemistry (Architect)

• Triglycerides: This could be a non-fasting sample, lipemia, or a transient rise during acute infection or illness. Repeat a fasting lipid profile once the patient is well. If it stays high, look for secondary causes (diabetes, hypothyroidism, nephrotic syndrome, drugs) or a primary hypertriglyceridemia. Persistent values this high carry a risk of pancreatitis.
• CRP and PCT: Together with the raised WBC and monocytes, these point to a bacterial or significant inflammatory process. The source is not shown by these tests.

Urine (UC-3500 and UF-4000)

• Blood 1+, protein trace (+-), pH 6.5.
• Specific gravity 1.005 (dilute).
• Urobilinogen normal.
• Ketones, glucose, bilirubin, nitrite and leukocyte esterase all negative.
• Color light yellow, clear.

• RBC 1.7/HPF, non-lysed RBC 1.6/HPF (essentially normal).
• WBC 18-20/HPF (pyuria).
• Squamous and non-squamous epithelial cells low.
• No casts, bacteria or crystals.
• Yeast cells appear to be marked "+", but the print is hard to read here. Please check the original.

• Pyuria with a negative leukocyte esterase and nitrite is discordant. In dilute urine (SG 1.005) white cells can lyse, and a negative nitrite is common in young children because urine does not stay in the bladder long enough.
• The analyzer comment "UTI?" plus raised CRP and PCT makes UTI a real possibility. Send a properly collected urine culture, ideally before antibiotics. Use a clean-catch, catheter or suprapubic sample in a child who is not toilet trained, not a bag specimen.
• Dipstick blood 1+ with only 1.7 RBC/HPF is not significant hematuria. Repeat the urine once the child is well.
• Trace protein in dilute urine is minor and likely related to the acute illness.

Suggested next steps

1. Correlate with fever and symptoms, and send a urine culture and a blood culture if febrile.
2. Look for other sources of infection (chest, ENT, skin, bone or joint) guided by examination.
3. Do an anemia work-up (smear, retic, iron studies, HPLC) and treat once the cause is confirmed.
4. Repeat fasting triglycerides after recovery.
5. Add an APTT if bleeding is a concern, and trend CRP.
