Los trastornos de lípidos se diagnostican con exámenes sanguíneos que miden el nivel de colesterol y triglicéridos en la sangre.

Análisis de sangre

Los niveles de colesterol se revisan con un examen sanguíneo. Se toma una pequeña muestra de sangre de una vena en su brazo. Usted podría necesitar ayunar durante varias horas, por lo general toda la noche, antes que se tome su muestra de sangre. El examen mide niveles de:

  • Colesterol total.
  • Colesterol LDL no saludable
  • Colesterol HDL saludable
  • Triglicéridos.

Las lecturas se interpretan de la siguiente manera:

Colesterol total

NivelInterpretación
<200 mg/dL (5.2 mmol/L)Deseable
200 a 239 mg/dl (5,2 a 6,1 mmol/l)Límite alto
240 mg/dl (6,2 mmol/l) o másAlto

Colesterol LDL

NivelInterpretación
menos de 100 mg/dL (2.6 mmol/L)Óptimo
100 a 129 mg/dl (2,6 a 3,3 mmol/l)Casi óptimo/ por encima del óptimo
130 a 159 mg/dl (3.4 a 4.0 mmol/l)Límite alto
160 a 189 mg/dl (4.1 a 4.8 mmol/l)Alto
>190 mg/dl (4,9 mmol/l) o másMuy alto

Colesterol HDL

NivelInterpretación
60 mg/dl (1.6 mmol/l) o másProtector contra enfermedades cardiacas
menos de 40 mg/dL (1.0 mmol/L)Un principal factor de riesgo para enfermedades cardiacas
