Meaning

Measurement of height from fundus of uterus to the upper border of symphysis pubis.
After 24 weeks, the SFH measured in cm. corresponds to the number of weeks up to 36 weeks. A variation of +/-2cm is accepted as normal. Variation beyond the normal range needs further evaluation (a lag of 4cm or more suggests growth restriction.) It is a fairly sensitive parameter (30-80%).
SFH = 24-36 weeks=[Gestational age +/-2 cm.]
Ex. If Gestational age is 28 weeks then the SFH is either 30 cm (28+2cm=30cm) or 26 cm (28-2cm=26cm).

Procedure

  • Explain the procedure to the mother to gain her confidence.
  • Instruct the mother to empty her bladder. Mother should lie flat on her back.
  • The upper border of the fundus is located by the ulnar border of the left hand and this point is marked.
  • The distance between the upper border of symphysis pubis up to the marked point measured by a tape in centimeter.
