Blood test
From last couple of months, I see a drastic platelets drop for my spouse.
2024, she got dengue & I believe it makes sense to drop. Later, she got effected again in August 2025 & now, few days back. Don't know what's going on.

Your spouse’s persistent and recurrent low platelet count (thrombocytopenia), especially with multiple dengue episodes (2024, August 2025, and recent), combined with a significantly prolonged APTT of 85.2 seconds (normal usually 25–35 seconds), is concerning and not typical for simple dengue recovery.
Dengue does cause platelet drop during acute phase, but:
• Platelets usually recover within 7–14 days after fever subsides in uncomplicated cases.
• Repeated dengue infections (especially secondary dengue) can cause more severe thrombocytopenia, but persistent low platelets months later + drastic recurrent drops + very prolonged APTT strongly suggest something beyond just dengue sequelae.
The prolonged APTT indicates a coagulation abnormality — likely deficiency or inhibitor in the intrinsic pathway (factors VIII, IX, XI, XII, or lupus anticoagulant / antiphospholipid antibodies).
This is not normal post-dengue and raises red flags for:
• Antiphospholipid syndrome (APS) — common cause of prolonged APTT + thrombocytopenia + recurrent thrombosis risk (even without clots yet)
• Immune thrombocytopenia (ITP) triggered or unmasked by dengue
• Acquired factor deficiency (rare post-viral)
• Liver dysfunction (mild subclinical — dengue can affect liver) — though LFT not shared
• Vitamin K deficiency or DIC (less likely without bleeding/fever)
The attached report appears to be an anti-cardiolipin antibody (aCL) test (IgG and IgM), but the values are not clearly readable in the image. It mentions “low/medium positive” in some units, which could support antiphospholipid syndrome if positive. This needs urgent clarification.
Next Steps
1. Urgent consultation (within 1–3 days) — do not wait:
• Hematologist (best choice for thrombocytopenia + prolonged APTT)
• Or Clinical immunologist / Rheumatologist (if APS suspected)
2. Essential tests to request immediately:
• Repeat platelet count (current level)
• Peripheral smear — to see platelet morphology & rule out pseudothrombocytopenia
• Full coagulation profile: PT, APTT mixing study (to differentiate factor deficiency vs inhibitor), fibrinogen, D-dimer
• Lupus anticoagulant (LA) (dRVVT method) + anti-cardiolipin IgG/IgM repeat (quantitative values)
• Anti-beta2 glycoprotein I antibodies (IgG/IgM) — completes APS workup
• ANA + anti-dsDNA (rule out SLE)
• Liver function tests (LFT) + ultrasound abdomen (liver/spleen size)
• Bone marrow aspiration — only if platelets
Health Tips
• Avoid aspirin, NSAIDs (ibuprofen, diclofenac), or any blood thinners until evaluated
• Avoid alcohol, smoking, herbal supplements — can worsen bleeding risk
• No heavy lifting, contact sports, or trauma
• Soft toothbrush, avoid forceful nose blowing
• Watch for red flags (go to emergency immediately):
• Bleeding gums, nosebleeds, blood in urine/stool
• Black stools, vomiting blood
• Sudden severe headache, vision change, weakness
• Bruising without cause
This is treatable — if dengue-related immune thrombocytopenia or early APS, steroids, IVIG, or hydroxychloroquine can control it. But urgent hematology evaluation is needed to prevent complications.
For a complete, step-by-step plan (which hematologist in your city is best for thrombocytopenia + prolonged APTT, exact tests to request, how to interpret anti-cardiolipin results, safest supportive care right now, and what to expect from treatment),
please book an online consultation with me — I’ll review the full report details, previous platelet trends, and current symptoms to give you a clear roadmap so you get the right diagnosis and treatment quickly and safely.
Looking forward to helping your spouse get stable and safe — book now and let’s resolve this urgently

The reason why still platelet counts are low might indicate some occult pathology which is going on and patient might be asymptomatic right now. Your reports show increased aPTT but the anticardiolipin is low positive which means it is not positive to currently diagnose the disease as APLA. So we need clinical history in terms of wasted pregnancies and other related autoimmune history to rule out autoimmune disorders like SLE. We do need other related lab workup which might include CBC, LFT, ANA, ANA profile, IPF(immature platelet fraction), DCT and other on the basis of these reports. You should get a CBC done monthly if your platelet count is above 50000. So you should consult and follow up as required

The blood reports you sent show that in the blood there is an ‘Abnormal Protein’ that is affecting the bloods clotting system.
Do the following,
1. Blood tests- CBP, ESR, KFT, Liver function test, Protein C, Protein S, Anti-Thrombin 3, Immunoglobulins, C3, C4, ANA, Anti-ds DNA, Anti-histone antibodies, Cryoglobulins, Rheumatoid factor, anti-CCP antibodies, Hepatitis B, Hepatitis C and HIV test
2. Urine - Mircoscopy and Albumin-Creatinine ratio
3. CT scan- chest, abdomen and pelvis
4. If any leg swelling- Doppler Ultrasound scan of the leg/s
5. If any history of headaches- MRI-V brain scan
6. See a Haematologist as she may need to be given blood thinning medication like Warfarin
All the best.
