Find the Right Clinical Reference Tool for Your Situation
These tools serve healthcare professionals, students, and informed patients who need quick access to standardized clinical calculations and screening scores. They implement published, validated instruments that appear in clinical practice — the PHQ-9, GAD-7, Glasgow Coma Scale, GLP-1 dosing guidelines, and others. Use them as reference aids alongside clinical judgment, not as standalone diagnostic tools.
Mental Health Screening Tools
Standardized screening questionnaires are the starting point for mental health assessment in primary care and psychiatric settings. The PHQ-9 Depression Screener implements the 9-item Patient Health Questionnaire with standard severity scoring — minimal (0-4), mild (5-9), moderate (10-14), moderately severe (15-19), severe (20-27). For anxiety, the GAD-7 Anxiety Screener uses the 7-item Generalized Anxiety Disorder scale with the same validated cutoffs. The PCL-5 PTSD Screener implements the 20-item PTSD Checklist for DSM-5, with a provisional diagnosis threshold of 33 or higher. For attention concerns, the ADHD ASRS Screener uses the World Health Organization's Adult ADHD Self-Report Scale. These tools present each question exactly as it appears in the validated instrument and calculate scores using standard clinical cutoffs.
GLP-1 Medications and Weight Management
GLP-1 medications (semaglutide, tirzepatide, liraglutide) have specific titration schedules and dose-response patterns. The GLP-1 Dosing Schedule maps out the standard titration timeline for the major medications, showing weekly dose escalation from starting dose to maintenance. The GLP-1 Weight Loss Calculator estimates projected weight loss based on clinical trial average response rates at each medication and dose. The GLP-1 Cost Calculator compares brand name versus compounded options with insurance scenarios, and the GLP-1 Protein Calculator helps users on these medications maintain adequate protein intake during weight loss to preserve lean body mass.
Clinical Assessment Tools
Clinical scoring tools provide standardized communication between care providers and consistent documentation. The Glasgow Coma Scale calculator scores eye, verbal, and motor responses (GCS 3-15) with standard severity thresholds: severe (≤8), moderate (9-12), mild (13-15). The APGAR Score Calculator computes the standard newborn assessment at 1 and 5 minutes on the five components (appearance, pulse, grimace, activity, respiration). The Epworth Sleepiness Scale screens for excessive daytime sleepiness, and the MMSE Cognitive Screener implements the 30-point Mini-Mental State Examination for cognitive assessment.
Medication Dosing and Clinical Reference
The Medication Dosage Calculator handles weight-based dosing calculations — commonly needed for pediatric dosing or medications dosed in mg/kg. Enter patient weight, prescribed dose, and concentration to verify the correct volume to administer. The IV Drip Rate Calculator converts medication orders to drops per minute or mL per hour for manual and electronic infusion settings. The Medication Half-Life Calculator shows drug concentration at any time point after the last dose, useful for understanding wash-out periods. The Needle Gauge Chart is a quick reference matching gauge numbers to outer diameter, inner diameter, and common use cases.
How These Tools Are Intended to Be Used
Healthcare professionals can use these tools as rapid calculation verification aids during clinical workflows, reducing manual arithmetic errors for weight-based dosing and infusion rate calculations. Students in nursing, pharmacy, and medical programs will find the clinical scoring tools helpful for learning the validated questionnaires and scoring methods used in practice. Patients and caregivers researching treatment options or trying to understand clinical scores mentioned during appointments can use these tools for educational context, always with the understanding that interpretation requires clinical judgment. The mental health screening tools are sometimes used by individuals in areas with limited mental health access as a starting point to understand their symptoms before seeking professional evaluation. In all cases, a positive screen or concerning result should prompt professional consultation, not independent action based on a calculator result alone. All tools in this section run entirely in your browser — no responses, scores, or personal health data are transmitted to any server or stored anywhere. This design is intentional for health-related tools where data sensitivity is high. Every calculation stays on your device and disappears when you close the browser tab. For clinical reference use, these tools are designed to reduce arithmetic errors and provide quick score lookups — the kind of calculations that are simple in principle but easy to miscount when done manually under time pressure. They're built to be fast: one input field, one result, no menus or navigation required. Clinical calculators that require navigating multiple screens or entering unnecessary patient demographics slow down the lookup process and increase friction. These tools prioritize the minimum inputs needed for the calculation and return the result immediately. For healthcare educators, the standardized scoring tools can also serve as teaching aids for students learning to administer and interpret validated instruments for the first time.
FAQ
Are these tools free?
Yes, every tool is completely free to use with no signup, no account, and no hidden fees.
Is my data safe?
Absolutely. All calculations run locally in your browser. No data is sent to any server or stored anywhere.
Do I need to create an account?
No. Every tool works instantly with no registration required. Just open and start using.
Are these tools suitable for clinical use?
These tools implement validated clinical instruments and are suitable as reference aids for healthcare professionals and students. They are not a substitute for clinical judgment, formal diagnostic evaluation, or consultation with a qualified clinician. Always verify calculations with your institution's protocols.
How accurate are the mental health screening scores?
The PHQ-9, GAD-7, PCL-5, and other screening tools implement the exact published questionnaire items and standard scoring algorithms. They produce the same scores a clinician would calculate manually. However, screening tools identify symptom severity ranges — they are not diagnostic instruments, and a positive screen always requires clinical follow-up.
Who are the GLP-1 calculators designed for?
The GLP-1 tools are for patients prescribed these medications (or considering them) who want to understand dosing schedules, project weight loss timelines, or compare costs between options. The dosing information reflects standard manufacturer titration schedules, but your prescribing physician's instructions take precedence.
Can I use the medication dosage calculator for pediatric patients?
The Medication Dosage Calculator supports weight-based dosing calculations, which is the standard approach for pediatric dosing. Always verify the dose, concentration, and route against the prescribing order and your formulary. For high-risk medications, independent double-check by a second clinician is standard practice.
What does the Glasgow Coma Scale score mean?
The GCS ranges from 3 (no response) to 15 (fully alert). Scores of 13-15 indicate mild injury, 9-12 moderate, and 8 or below severe neurological impairment. A score of 8 or below is the clinical threshold commonly used for airway management decisions. The GCS Calculator scores each of the three components (eyes, verbal, motor) separately before computing the total.
