About this mock
This mock tests applied forensic serology and bloodstain pattern analysis at the practical level — the reagents, techniques, and interpretation scenarios that appear in casework and on FACT and NFSU examination papers. It assumes the foundational serology module is complete and pushes directly into application: how to collect a wet stain, how to run a differential extraction on a mixed stain, how to interpret an azoospermia scenario, how to calculate angle of impact, and how to navigate the secretor-status typing workflow.
It is pitched at second-year BSc and MSc forensic science students at NFSU and LNJN-NICFS who have completed the foundational serology and DNA modules, and at FACT and UGC-NET candidates who need technique-level knowledge consolidated before examination.
Topics covered:
- Differential extraction for mixed male and female biological stains
- Bloodstain pattern interpretation: cast-off, arterial spurt, wipe vs swipe, void patterns, contact transfer
- Area of origin stringing technique and angle of impact formula (sin θ = W/L)
- ALS wavelengths for body fluid fluorescence and blood visualisation
- RSID strip tests for species-specific fluid identification
- Y-STR profiling for male contributor identification in mixed stains
- Secondary transfer and touch DNA thresholds in practical casework
- Menstrual blood identification using MMP-10 mRNA markers
- Hair root vs hair shaft: nuclear DNA vs mitochondrial DNA recovery
- Urine identification (urea, creatinine, urease test)
- Christmas Tree staining for spermatozoa confirmation
- Bite mark double-swab technique and salivary amylase recovery
- Azoospermia scenario: PSA/p30 positive, sperm-negative interpretation
- MoHFW rape kit examination timing guidelines
- ABO and Rh blood group distribution in the Indian population
- Mini-STR kits for degraded and old biological samples
- Wet stain collection protocols and dry stain scraping method
- Absorption-inhibition and absorption-elution ABO typing from stains
- ABO typing from secretor-status seminal stains
- CFSL STR loci panels and CODIS compatibility
Each question carries a detailed explanation covering the mechanism of the correct answer, why each wrong option fails, and where the topic appears in FACT, NFSU, or UGC-NET syllabi. Allow 30 minutes.
