Kev tshuaj lom yog ib qho ntawm feem ntau cov txheej txheem thiab cov kws tshaj lij hauv cov hauj lwm ntawm kev paub txog kev ua txhaum cai. Kev ntsuas tshuaj lom cov tshuaj muaj ntau yam tshuaj lom, tshuaj, thiab siv yeeb tshuaj, thiab ntau pua yam ntawm lawv muaj. Kuaj qhov zoo yog siv cov tshuaj uas yog tsim nyog los yog ntau txog tshuaj lom thiab cov tshuaj txhaum cai uas siv lub cev los tshuaj tshuaj.
Lub Tsev Kuaj Mob Hluav Taws Xob hauv Lub Tsev Hais Plaub Ua Haujlwm ntawm Lub Chaw Haujlwm Saib Xyuas Kev Ruaj Ntseg / Cov Neeg Tiv Thaiv. Cov ntaub ntawv hluav taws xob rov qab thiab tshuaj xyuas yog qhov kev tawm tshiab ntawm kev tshuaj xyuas kev tshawb fawb tam sim no thiab thev naus laus zis. Nws tsis yog tsuas yog hom tshiab ntawm kev qhia kom paub, tab sis kuj yog qhov tseem ceeb thiab txoj kev txhim kho tseem ceeb rau kev tshawb nrhiav cov neeg tshawb fawb. Lub Tsev Kuaj Xyuas Hluav Taws Xob (Electronic Evidence Laboratory) ntawm Lub Chaw Hais Plaub Kev Txiav Txim Siab raug tsim tsa raws li cov qauv ntawm lub teb chaws kev lees paub lub chaw. Lub luag haujlwm tseem ceeb ntawm kev sim muaj lub xov tooj txawb forensics, cov ntaub ntawv rov qab, kev txheeb xyuas tus kheej, tus lej zais thiab lub network forensics, thiab lwm yam.
