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.

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.
