INTERFERENCIAS BIOQUÍMICAS POR TRATAMIENTO CON HIDROXICOBALAMINA
Figure. Cobalamin structure is composed of six valence cobalt atom. Four of them form a covalent bond with nitrogen atoms. The fifth valence forms a bond with the bencimidazole nitrogen. The sixth valence forms a bond with various anionic groups: A) hidroxicobalamin with hydroxyl group (OH-) and B) cianocobalamin with cyanide group (CN-). C) Reddish coloration of serum, characteristic of treatment with hydroxycobalamin in the patient’s sample.

RISO UN NUEVO ENFOQUE DE GESTIÓN DE LA ACTIVIDAD EN EL LABORATORIO CLÍNICO
Figure 1. FIFO, LIFO and RISO modes. Different options and priorities. There are two urgent samples, one detected at reception5 and another that goes unnoticed as routine3.

The terms FIFO, LIFO and FEFO are commonly used in management (Table 1).

Can be applied to samples and response times, when considering "expiration" as "commitment of response". Every laboratory follows different procedures. However, FIFO-routine and LIFO-urgency approach are frequent. Specific manual entries for emergencies in the analyzers are applied. There is a coexistence of two laboratories: routine and urgency.

PALUDISMO POR PARASITACIÓN MIXTA CON PLASMODIUM FALCIPARUM Y PLASMODIUM MALARIAE

Written by Arturo González Raya | Ramón Coca Zúñiga

PALUDISMO POR PARASITACIÓN MIXTA CON PLASMODIUM FALCIPARUM Y PLASMODIUM MALARIAE
Figure 1. Microscopic examination (100x) of Wright-Giemsa stained peripheral blood smear from the patient revealed ring forms of Plasmodium parasites. P. falciparum rings have delicate cytoplasm and one or two small chromatin dots.

We present a case of a male from Ghana who lives in Spain and comes back after visiting his country for the first time in 10 years. He received malarial chemoprophylactic treatment for 3 weeks (before and during the trip), but not after the return.
