Alvarado Score: -
Interpretation: Awaiting input...

Pain typically starts near the navel and
migrates to the right lower abdomen
as the appendix becomes inflamed.

Information:
The Alvarado Score estimates the likelihood of acute appendicitis based on symptoms and lab findings.

• 1–4: Low probability (Appendicitis unlikely)
• 5–6: Intermediate probability
• 7–10: High probability (Appendicitis likely)

Absolute Eosinophil Count (AEC) — Quick Calculator

Enter Eosinophil percentage and total WBC to compute AEC. Designed for mobile-first, accessible use and clear copy-ready output.

Eosinophils (%)

Percentage of eosinophils from differential count.

White Blood Cell (WBC) — ×10³ cells/µL

Enter WBC as ×10³ per µL (common lab reporting format).

(same result expressed in ×10³ units)

Result guidance

This AEC is a calculated value for rapid reference. It does not replace clinical evaluation. Abnormal values may be associated with allergic conditions, parasitic infections, or other causes. Consult a clinician for interpretation and next steps.

For clinicians (calculation details)

AEC (cells/µL) = (Eosinophils % / 100) × WBC (×10³/µL) × 1000. The tool displays both cells/µL and ×10³ cells/µL formats for convenience.

Animated: How AEC is formed

Visual explanation

Enter values and watch the animated bloodstream where eosinophils (orange cells) pulse proportionally to the calculated AEC. Great for patient education and quick clinician explanation.

Absolute Lymphocyte Count (ALC) — Quick 

Information

Absolute Lymphocyte Count (ALC) is a measure of the number of lymphocytes in the blood, calculated from the total white blood cell count and the percentage of lymphocytes. It is used in the evaluation of various conditions including immune disorders, certain infections, and some types of cancer.

Quick Clinical Tool-Absolute Neutrophil Count (ANC) Calculator

Heematology and Oncology

Heematology and Oncology

 

Information

Absolute Neutrophil Count (ANC) is a key measure of immune function, calculated from the total white blood cell count and the percentage of neutrophils (including both segmented neutrophils and bands). It is used to assess the risk of infection, particularly in patients undergoing chemotherapy, as a low ANC (neutropenia) can indicate a higher risk of infection. The ANC is guides treatment decisions, such as the initiation of antibiotics or the modification of chemotherapeutic regimens and is an important in the management of patients with conditions that affect white blood cell production or function.

Bands (%)

SevereModerateMildNormal

How ANC is calculated

ANC = WBC (×10³ cells/µL) × (Neutrophils% + Bands%) / 100. Example: WBC 6.0, neutrophils 55%, bands 4% → ANC = 6.0 × (55+4)/100 = 3.54 ×10³ cells/µL.

Interpretation & Suggested actions

• ANC < 0.5 ×10³/µL — Severe neutropenia. High infection risk. Consider urgent clinical review and protective isolation; discuss empiric antibiotics per local protocols.
• 0.5 — 1.0 ×10³/µL — Moderate neutropenia. Increased infection risk; consider close monitoring and infection precautions.
• 1.0 — 1.5 ×10³/µL — Mild neutropenia. Low-moderate risk; observe and repeat CBC as indicated.
• >= 1.5 ×10³/µL — Generally considered normal neutrophil count for adults.

This tool provides general guidance only. Always interpret in the clinical context and follow local guidelines.

Information 

 The SOFA Score (Sequential Organ Failure Assessment) is a tool used to assess the severity of organ dysfunction in critically ill patients. It evaluates six organ systems: respiration, coagulation, liver, cardiovascular, central nervous system, and renal. The score ranges from 0 to 24, with higher scores indicating greater organ dysfunction.

Tool-Child–Pugh Score — Chronic Liver Disease

Hematology 

Heematology and Oncology- 

The Child-Pugh Score is used for assessing the prognosis of chronic liver disease, especially cirrhosis. It evaluates liver dysfunction using five clinical measures: total bilirubin, serum albumin, prothrombin time or INR, ascites, and hepatic encephalopathy. Patients are classified into three categories reflecting disease severity. This scoring system is essential in determining treatment strategies, evaluating liver transplant needs, and in clinical research, including patient stratification in trials.
