Summary
This study details spurious neutropenia due to EDTA-dependent neutrophil agglutination. Kanamycin resolved this in vitro issue, a novel application for pseudo-neutropenia.
Area of Science:
- Hematology
- Clinical Pathology
Background:
- EDTA-dependent pseudo-neutropenia is a rare condition.
- In vitro neutrophil agglutination can mimic true neutropenia.
Observation:
- Neutrophils agglutinated in vitro in an EDTA-dependent manner.
- Agglutination persisted upon warming to 37°C but resolved with kanamycin.
Findings:
- This is the first report of kanamycin effectively resolving EDTA-dependent pseudo-neutropenia.
- The mechanism involves overcoming in vitro neutrophil agglutination.
Implications:
- Kanamycin offers a potential solution for diagnosing EDTA-dependent pseudo-neutropenia.
- This finding expands therapeutic strategies for laboratory artifact-induced cytopenias.

EDTA: Auxiliary Complexing Reagents
EDTA titrations are usually carried out in highly basic conditions, where the fully deprotonated form of EDTA, Y4−, actively complexes with the free metal ions in the solution. Several metal ions precipitate as hydrous oxide (hydroxides, oxides, or oxyhydroxides) under these conditions, lowering the concentration of free metal ions in the solution. For this reason, auxiliary complexing agents or ligands such as ammonia, tartrate, citrate, or triethanolamine are used in EDTA titrations to...
Effects of EDTA on End-Point Detection Methods
Different methods, such as visual observance of metal-ion indicators, spectroscopic techniques, and potentiometric methods, can determine the endpoint of an EDTA titration.
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a result, EDTA...

Masking and Demasking Agents
EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on the metal...

Determination of Multiple Dosing Parameters: Steady-State, Minimum and Maximum Concentrations
Gentamicin, an aminoglycoside antibiotic, is commonly administered via intermittent intravenous infusion to treat severe infections. An intermittent one-hour infusion of gentamicin, administered at eight-hour intervals, allows for precise control of plasma drug concentrations, minimizing toxicity while ensuring therapeutic efficacy. Pharmacokinetic principles govern the dynamics of plasma concentrations and can be mathematically described using specific equations.The plasma drug concentration...
