This calculator uses the PHQ-2 and PHQ-9 questionnaires to screen for depression symptoms and assess their severity. The PHQ-2 is a quick screening tool, while the PHQ-9 provides a more detailed assessment.
FEV1/FVC Ratio Calculator
Calculates the ratio of forced expiratory volume in 1 second (FEV1) to forced vital capacity (FVC) from spirometry, aiding lung disease diagnosis.
APGAR Score Calculator
This calculator determines the APGAR score of a newborn, a quick assessment of the baby's health at 1 and 5 minutes after birth. It evaluates Appearance (skin color), Pulse (heart rate), Grimace (reflex irritability), Activity (muscle tone), and Respiration (breathing effort).
Max Heart Rate Calculator
Estimates maximum heart rate based on age. Several formulas exist, providing different estimates.
Drug Half-Life Calculator
Estimates how long it takes for half of a drug dose to be eliminated from the body.
INR Calculator
Calculates the International Normalized Ratio (INR) for patients on warfarin anticoagulant therapy. This calculator uses the prothrombin time (PT) of the patient and the International Sensitivity Index (ISI) of the thromboplastin reagent used in the PT test.
ANC Calculator
Calculates the Absolute Neutrophil Count (ANC), which is the number of infection-fighting white blood cells (neutrophils) in the blood. This calculation is crucial for assessing a patient's risk of infection, particularly in individuals undergoing chemotherapy or with certain medical conditions.
Sodium Correction Calculator
Calculates the corrected serum sodium level in cases of hyperglycemia.
Diabetes Risk Calculator
Assesses the risk of developing type 2 diabetes based on factors like age, weight, family history, and physical activity.
Waist to Height Ratio Calculator
Calculates the ratio of waist circumference to height, assessing central obesity risk.
