Here is a full interpretation of the lab report for Shanti/Rajendra, 49-year-old female, dated 23/06/2026 from Vedant Diagnostics:
Lab Report Summary
HEMATOLOGY
| Test | Result | Normal Range | Status |
|---|---|---|---|
| Haemoglobin | 11.1 gm% | 11-14 gm% | Low-normal (borderline) |
| Total Leucocyte Count | 8,600 /cumm | 4,000-11,000 /cumm | Normal |
| Neutrophils | 65% | 40-70% | Normal |
| Lymphocytes | 31% | 20-40% | Normal |
| Monocytes | 2% | 2-8% | Normal |
| Eosinophils | 2% | 1-6% | Normal |
| Basophils | 0% | 0-1% | Normal |
| Platelet Count | 2.93 Lakh/cumm | 1.50-4.50 Lakh/cumm | Normal |
| Blood Group | AB Positive | - | - |
| Bleeding Time | 2 min 30 sec | 1-5 min | Normal |
| Clotting Time | 5 min 15 sec | 3-9 min | Normal |
BIOCHEMISTRY
| Test | Result | Normal Range | Status |
|---|---|---|---|
| Random Blood Sugar (RBS) | 102 mg/dl | 70-140 mg/dl | Normal |
| Urea | 18 mg/dl | 10-50 mg/dl | Normal |
| Serum Creatinine | 0.87 mg/dl | 0.6-1.2 mg/dl (F) | Normal |
SEROLOGY
| Test | Result | Status |
|---|---|---|
| Hepatitis B Surface Antigen | Non-Reactive | Normal |
| VDRL | REACTIVE | ABNORMAL |
| HIV 1 | Non-Reactive | Normal |
| HIV 2 | Non-Reactive | Normal |
Key Finding: VDRL REACTIVE
The most significant finding is a reactive VDRL, which is highlighted on the report. The lab has correctly noted: "To be confirmed by TPHA."
What this means:
- VDRL is a screening test for syphilis (caused by Treponema pallidum). A reactive result means the test detected anti-cardiolipin antibodies.
- VDRL has a false-positive rate - it can be reactive in conditions like malaria, lupus (SLE), antiphospholipid syndrome, pregnancy, viral infections, and tuberculosis.
- TPHA (Treponema pallidum Hemagglutination Assay) is a confirmatory, treponemal-specific test. If TPHA is also positive, syphilis is confirmed.
Next steps (as noted by the lab):
- Get TPHA (or TPPA/FTA-ABS) done immediately to confirm or rule out syphilis.
- Consult a physician - if confirmed, syphilis is treatable with penicillin.
- Do not ignore this finding even if the patient feels well - syphilis can be asymptomatic, especially in secondary or latent stages.
Other Notes
- Haemoglobin at 11.1 gm% is at the lower end of the normal range for females. It may reflect mild anemia and is worth monitoring. Iron studies, B12, and folate may be considered.
- All kidney function tests (urea, creatinine), blood sugar, blood counts, and platelet counts are within normal limits.
- HIV and Hepatitis B are non-reactive (negative).

Here is a synthesis of the most current guidelines on syphilis testing and management, directly relevant to this patient's reactive VDRL:
Syphilis Testing & Management: Current Guidelines (2024-2025)
Key Guideline Sources
- CDC Laboratory Recommendations for Syphilis Testing 2024 (MMWR 2024)
- CDC STI Treatment Guidelines (updated Oct 2024)
- WHO Updated Recommendations for Syphilis Testing & Treatment (July 2024)
- BASHH UK Guidelines for Syphilis Management 2024 [PMID: 39270129]
1. Diagnostic Testing Algorithm
Screening Tests (Nontreponemal - like this patient's VDRL)
- VDRL and RPR detect anti-cardiolipin (lipoidal) antibodies - they are not syphilis-specific
- They become reactive 4-5 weeks after infection
- Used for screening and for monitoring treatment response (titers fall after successful treatment)
- A fourfold reduction in titer = confirmed treatment response
- VDRL and RPR are NOT interchangeable - follow-up must use the same test type
Confirmatory Tests (Treponemal - what this patient needs next)
- TPHA / TPPA (Treponema pallidum Hemagglutination / Particle Agglutination) - preferred manual confirmatory test per CDC 2024
- FTA-ABS (Fluorescent Treponemal Antibody Absorption)
- EIA/CIA (Enzyme/Chemiluminescence Immunoassay) - used in "reverse sequence" algorithm
Per CDC 2024: "Sole reliance on one reactive serologic test result can misclassify a patient's syphilis status." Both traditional (nontreponemal first) and reverse (treponemal first) algorithms are acceptable.
Interpreting Results for This Patient
| VDRL | TPHA/TPPA | Interpretation |
|---|---|---|
| Reactive | Reactive | Likely true syphilis - stage and treat |
| Reactive | Non-reactive | Probable false positive - investigate (lupus, pregnancy, malaria, viral infections, elderly) |
| Non-reactive | Reactive | Possible late syphilis, or treated past infection - repeat VDRL in 2-4 weeks |
WHO 2024 New Recommendations
- Dual treponemal/nontreponemal Rapid Diagnostic Tests (RDTs) are now endorsed as an additional option - useful in outreach or low-resource settings
- Syphilis self-testing is now also recommended as an additional option for STI services
2. Staging (Required Before Treatment)
After confirmatory testing, the patient must be staged:
| Stage | Features |
|---|---|
| Primary | Painless chancre (genital ulcer), usually heals in 3-6 weeks |
| Secondary | Rash (palms/soles), condyloma lata, fever, lymphadenopathy |
| Early latent | Positive serology, no symptoms, infection within past 12 months |
| Late latent | Positive serology, no symptoms, >12 months or unknown duration |
| Tertiary | Gummas, cardiovascular, or neurosyphilis |
3. Treatment Recommendations
First-line Treatment (all stages)
Benzathine Penicillin G (IM injection) remains the definitive treatment per CDC, WHO, and BASHH 2024:
| Stage | Regimen |
|---|---|
| Primary, secondary, early latent | Benzathine penicillin G 2.4 million units IM single dose |
| Late latent / tertiary (non-neuro) | Benzathine penicillin G 2.4 million units IM x 3 doses (weekly for 3 weeks) = 7.2 MU total |
| Neurosyphilis | Aqueous crystalline penicillin G 18-24 million units/day IV for 10-14 days |
Penicillin Allergy
- Doxycycline 100 mg orally twice daily x 14 days (early syphilis) or x 28 days (late latent)
- Note: Azithromycin is no longer recommended due to widespread resistance
Syphilis in Pregnancy (per WHO 2024 update)
- Benzathine penicillin G remains first-line
- Amoxicillin is now recommended as second-line for pregnant women with penicillin allergy (WHO 2024 update)
- The USPSTF reaffirmed in June 2025 [PMID: 40358930] that all pregnant women should be screened for syphilis at first prenatal visit
4. Post-Treatment Monitoring
- Repeat nontreponemal titer (VDRL or RPR) at 6 and 12 months after treatment
- Treatment success = fourfold (2-dilution) decline in titer
- Treatment failure = fourfold rise in titer (consider re-treatment and CSF examination)
- Treponemal tests (TPHA/FTA-ABS) remain positive for life - do NOT use them to monitor response
5. Jarisch-Herxheimer Reaction
Patients must be warned of this reaction occurring within 24 hours of first treatment:
- Acute fever, headache, myalgia, chills
- Caused by cytokine release from dying spirochetes
- Managed with paracetamol (acetaminophen)
- Not an allergic reaction - treatment should not be stopped
Summary for This Patient (Shanti, 49F, VDRL Reactive)
- Next step: TPHA or TPPA confirmatory test immediately
- If TPHA is positive: clinical examination to stage the infection, then treat accordingly
- If TPHA is negative: investigate for false-positive causes (autoimmune disease, recent viral illness, etc.)
- Partner notification and testing is required if syphilis confirmed
- Refer to a physician/sexual health specialist - do not delay
