GlobalRPh Clinical Reference Library

Hematology, Anemia, Thrombosis & Blood Disorders Resource Center

Anemia and iron-deficiency tools, ANC and neutropenia resources, VTE and anticoagulation calculators, platelet and bleeding references, hemoglobin disorders, hemophilia and gene-therapy updates, hematologic malignancy articles, IV iron preparation, and current GlobalRPh hematology resources.

Clinical background

Hematology connects blood counts with marrow function, hemostasis, thrombosis and systemic disease

A low hemoglobin, abnormal platelet count, neutropenia or thrombotic event rarely stands alone. Hematologic abnormalities can reflect nutritional deficiency, chronic inflammation, renal disease, immune destruction, medication effects, infection, inherited disorders, marrow failure, malignancy, bleeding, hemolysis, thrombosis or a combination of processes.

This updated portal brings GlobalRPh’s hematology calculators, anemia and iron resources, anticoagulation tools, coagulation drug tables, IV iron references, and the much larger 2025–2026 hematology article library into one organized center. Hematologic oncology content remains visible here, with a clear handoff to the Oncology portal for broader cancer-treatment resources.

Red cells Anemia, iron status, hemolysis, hemoglobin disorders and erythrocytosis.
White cells ANC, neutropenia, marrow disorders and hematologic malignancy.
Platelets Thrombocytopenia, ITP, TTP, drug causes and platelet-directed therapy.
Coagulation VTE, heparin, warfarin, HIT, bleeding, thrombolysis and inherited disorders.

Core GlobalRPh calculators

Hematology, anemia and anticoagulation tools

The original Hematology portal contains a strong calculator collection. It is reorganized below by clinical purpose, with additional closely related GlobalRPh tools included where they improve the workflow.

Anemia & iron disorders

Diagnostic tools, iron replacement and newer interpretation resources

GlobalRPh has an unusually deep iron-deficiency collection. The revised section separates diagnosis from replacement calculations and IV product preparation.

Ferritin is an acute-phase reactant, so iron deficiency can be harder to recognize in inflammatory disease, chronic kidney disease, heart failure and other systemic conditions. We are updating the anemia pathway to better distinguish absolute iron deficiency from functional iron restriction and mixed etiologies.

Thrombosis & anticoagulation

VTE diagnosis, anticoagulant dosing, cancer-associated thrombosis and HIT

VTE decision rules should be used within an appropriate diagnostic pathway. Pretest probability, D-dimer strategy, imaging, pregnancy, active cancer, renal function, bleeding risk, hemodynamic stability and prior anticoagulant exposure can materially change management.

Warfarin & anticoagulation reversal

Existing GlobalRPh warfarin tools

These resources remain useful for institutions and patients who still require warfarin, but several were built around older ACCP-era nomograms. We are retaining them while modernizing the clinical context and reversal guidance.

Platelets, bleeding & thrombotic microangiopathy

Thrombocytopenia, ITP, TTP and platelet-directed therapy

Neutropenia, marrow failure & cytopenias

ANC, drug-associated neutropenia and marrow-disorder resources

An ANC is a useful numeric measure, but the clinical meaning of neutropenia depends on severity, duration, fever, chemotherapy or immunosuppression, medication exposure, infection, marrow reserve and the patient’s overall immune status.

Hemoglobin disorders & red-cell biology

Sickle cell disease, G6PD deficiency, hemochromatosis and erythrocytosis

G6PD deficiency

Drug-risk lists for G6PD deficiency have changed over time as evidence quality has improved. This page is on our planned-update list so risk categories and testing caveats can be clarified.

Hemophilia, VWD & inherited bleeding disorders

Gene therapy, non-factor prophylaxis and current bleeding-disorder guidance

Hematologic malignancy

AML, CLL, MDS, CAR-T and marrow-microenvironment updates

Hematologic oncology belongs in both Hematology and Oncology. This portal surfaces the major GlobalRPh hematology articles, while broader cancer-treatment content remains in the Oncology section.

Looking for broader cancer-treatment resources?

Hematology will continue to surface leukemia, lymphoma, myeloma, MDS, transplantation and cellular therapy content, while chemotherapy protocols, solid-tumor treatment, oncologic toxicity and the broader cancer library remain centered in GlobalRPh Oncology.

GlobalRPh hematology article library

Recent and established hematology reading

The previous portal surfaced only a small group of 2024 articles. This section brings forward the much larger 2025–2026 GlobalRPh Hematology archive.

Existing hematology videos now surfaced on the portal

The old Hematology page displayed only one video even though the GlobalRPh video library now has a substantial hematology collection.

Planned GlobalRPh updates

Areas we’re continuing to improve in the Hematology library

GlobalRPh has maintained many hematology and anticoagulation tools for years, while diagnostic methods, iron therapy, thrombosis management, reversal strategies and hematologic oncology have changed rapidly. As we work through this section, we plan to update the clinical logic and references first, then improve the individual interfaces.

Pages we plan to refresh

  • Anemia Diagnostic Flowchart: we plan to update the older reference base and build a clearer pathway around MCV, reticulocyte response, iron studies, B12/folate, hemolysis, kidney disease, inflammation, marrow disease and bleeding.
  • Iron Deficiency Anemia / IDA vs Anemia of Chronic Disease: we plan to strengthen ferritin and transferrin-saturation interpretation in inflammatory states and add contemporary context for functional iron deficiency, reticulocyte hemoglobin measures, soluble transferrin receptor and mixed etiologies.
  • Iron Deficit Multi-Calc and Iron Dextran tools: we plan to update these beyond older Cosmofer/Infed-centered approaches and incorporate current IV iron products, product-specific maximum doses, infusion requirements, adverse reactions and labeling.
  • Oral & Parenteral Iron Products: we plan to update currently marketed preparations, elemental-iron content, oral dosing strategies, absorption interactions, IV formulations and practical selection considerations.
  • Elevated INR / Warfarin reversal: the current page relies heavily on older ACCP guidance. We plan to update vitamin K use, bleeding severity, four-factor PCC, plasma, drug interactions, urgent reversal and links to current anticoagulation guidance.
  • Warfarin nomograms: we plan to preserve useful institutional examples while clearly separating historical nomograms from contemporary patient-specific initiation, maintenance, peri-procedural and interaction management.
  • Heparin dosing: we plan to update VTE/ACS distinctions, obesity, aPTT versus anti-Xa monitoring, renal considerations, protocol customization, bleeding surveillance and HIT evaluation.
  • Argatroban / DTI page: we plan to rebuild this as a dedicated direct-thrombin-inhibitor and HIT resource rather than leaving it inside older mixed IV medication material.
  • Wells PE / DVT: we plan to retain these validated rules while adding current diagnostic-pathway context, including D-dimer strategies, age adjustment where appropriate, imaging and special-population limitations.
  • ANC / neutropenia: we plan to update the background discussion, febrile-neutropenia context, medication causes, growth-factor links and contemporary interpretation of baseline neutrophil variation.
  • Colony-Stimulating Factors: we plan to remove obsolete products, update G-CSF/ESA agents and biosimilars, modernize hemoglobin-target language and improve oncology/CKD cross-linking.
  • Thrombocytopenia causative list: we plan to update medication causes and add a clearer differential approach for pseudothrombocytopenia, sepsis/DIC, HIT, immune thrombocytopenia, TMA and marrow disease.
  • TPO-receptor agonists: the current portal effectively points to eltrombopag alone. We plan to build a class-level reference covering current agents, indications, liver considerations, platelet targets and ITP/aplastic-anemia context.
  • G6PD deficiency: we plan to update medication-risk categories, evidence quality, quantitative testing considerations and the limitations of testing during or soon after acute hemolysis.
  • Antiplatelets / LMWH / DTIs / thrombolytics: we plan to verify current product availability, renal dosing, indications, reversal strategies, monitoring and contemporary role within cardiovascular and VTE treatment.
  • New hematology tools: we plan to evaluate adding dedicated decision-support for HIT (4Ts), TTP/TMA assessment, DIC scoring, reticulocyte production, corrected reticulocyte count and other high-value hematology workflows before adding calculators simply to expand the list.
HIT decision support Evaluate a GlobalRPh 4Ts-based workflow linked to current ASH HIT guidance.
TTP / TMA assessment Evaluate PLASMIC-style and differential-support tools with clear limitations.
DIC scoring Evaluate current scoring-system implementation with sepsis/critical-care cross-links.
Reticulocyte interpretation Consider corrected reticulocyte count / production-index support for anemia workflows.
Modern iron dashboard Combine ferritin, TSAT, CBC indices, inflammation and replacement planning.
Anticoagulation reversal center Consolidate warfarin and modern anticoagulant reversal into one current reference.
Our goal is to preserve the established calculators that clinicians and pharmacists already use while making current evidence, limitations, monitoring and high-risk safety considerations easier to see.

Why we retain historical anticoagulation and anemia tools during the update process

Some GlobalRPh pages contain calculations or institutional nomograms that remain useful even though their explanatory references need updating. We are preserving those links while we review the clinical assumptions, current guideline context, product availability and safety language so users do not lose access to longstanding resources during the modernization process.
