Get a PT / INR (Prothrombin Time) test at VRX Diagno Lounge, Goregaon West the standard test to monitor warfarin / acitrom therapy, screen for clotting disorders, and assess liver synthetic function. No fasting needed. Pathologist-reviewed report by evening. 24×7 home collection.
The Prothrombin Time (PT) measures how long blood takes to clot via the extrinsic and common coagulation pathways. The INR (International Normalised Ratio) standardises this across laboratories and is the global standard for monitoring oral anticoagulants like warfarin (Acitrom). PT is also used to detect liver disease, vitamin K deficiency, DIC, and inherited factor deficiencies.
INR is the standard for dose adjustment most patients target INR 2.0–3.0 (some 2.5–3.5)
Liver makes most clotting factors prolonged PT signals advanced liver disease
Common in newborns, malabsorption, prolonged antibiotic use
Routine before invasive surgery to ensure normal clotting
Severe illness with consumption of clotting factors
Helps screen for Factor II, V, VII, X deficiencies
INR every 1–4 weeks once stable; more often when starting therapy or interacting drugs
Routine baseline before any invasive procedure
Prolonged PT is part of MELD score for liver-disease severity
Easy bruising, prolonged bleeding from cuts, gum bleeding
Long-course antibiotics deplete gut vitamin K
Vitamin K deficiency bleeding screen
DIC screening in sepsis or severe trauma
Inherited factor deficiencies are screened with PT/aPTT
| Parameter | What It Measures | Reference Range |
|---|---|---|
| PT (normal) | Prothrombin Time | 11–14 seconds (lab-dependent) |
| INR (normal no anticoagulant) | Healthy adult | 0.9–1.1 |
| INR target atrial fibrillation / DVT | Most warfarin indications | 2.0–3.0 |
| INR target mechanical heart valve | Higher target | 2.5–3.5 |
| INR > 5.0 | Increased bleeding risk | Reduce or hold warfarin |
| % Activity (PT activity) | Activity expression | 70–120% |
PT and INR within reference range and no medication signal normal extrinsic coagulation. Continue routine yearly screening if you have risk factors.
Prolonged PT/INR in someone not on warfarin = liver disease, vitamin K deficiency, or factor deficiency. In warfarin patients value is interpreted relative to target. Your physician will correlate with symptoms and history.
Every report is reviewed by an experienced pathologist with clear interpretation and clinical comment.
If further evaluation is needed aPTT, Liver Function Test, CBC, D-Dimer, Factor assays all available at the Goregaon West centre.

Truly appreciated the personal attention and professional approach during my aqua therapy sessions. The physiotherapist explained everything clearly. Highly recommended for anyone needing supervised pool-based rehab.
Started here after my knee surgery on my doctor's recommendation. The 1-on-1 sessions made a real difference and the team was supportive and patient throughout my recovery process. Worth every visit.
My mother has been visiting VRX Goregaon for arthritis-related sessions. The staff is patient, the centre is clean and well-maintained, and the pricing is transparent exactly what we were looking for.
Detailed initial consultation, no rushed appointments. The aqua therapy approach felt much gentler on my joints than regular gym workouts. Will continue here for the foreseeable future.
Easy to book, professional team, and a well-maintained therapy pool. I felt reassured by the close supervision throughout each session. Worth the visit if you need supervised aqua therapy in Mumbai.
Have visited multiple physio centres, but the depth of attention at VRX is genuinely different. They actually adapt the plan as you progress instead of giving everyone the same routine.
